Multifunctional cementitious composite: Conductive and auxetic behavior

This research focused on developing an innovative multifunctional cementitious material with both conductive and auxetic properties simultaneously. This novel cement-based metamaterial has different applications, ranging from piezoresistivity to structural energy dissipation. The cementitious composite (CC) with an auxetic structure were produced using additive manufacturing techniques. The study involved analyzing different cementitious compositions, including Ultra High-Performance Concrete (UHPC) formulation tailored for both high strength and workability, and flexible mortar. Both types of composites were combined with two types of fibers: recycled carbon and Polyvinyl Alcohol (PVA). Uniaxial compression tests, conductivity, piezoresistivity by load cycles, and Digital Image Correlation (DIC) analysis were carried out on the auxetic cementitious composite (ACC). Among these tested cementitious composites (UHPC and flexible mortar) reinforced with PVA and recycled carbon fibers, only the flexible mortar with carbon fibers achieved the desired multifunctional properties. This success with flexible mortar and carbon fibers suggests promise for this combination. Conversely, UHPC composites with PVA fibers, with or without additional carbon fibers, failed to achieve the targeted functionality. As a result, both piezoresistivity and auxetic properties were achieved. From the auxetic behavior results, the Poisson’s ratio reached -67.5%. This implies that if compressed longitudinally, the specimen is shortened transversely (auxetic behavior) by up to 67.5%. This finding stands out compared to traditional construction materials like concrete and steel, which typically exhibit much lower strain recoveries (15–30%). On the other hand, the specific deformation energy absorption of the auxetic specimen reached 0.076 Jcm3. Moreover, the resistivity reached the small magnitude of 0.15 Ωm at 50 Hz, proving to be a conductive composite. The gauge factor of 4.26 indicates that it can be used as a self-sensing concrete. This innovative cementitious composite opens new possibilities for future applications that require materials with conductive and auxetic behaviors.

MXene Crosslinked Hydrogels with Low Hysteresis Conferred by Sliding Tangle Island Strategy.

Single-network hydrogels are often too fragile to withstand mechanical loading, whereas double-network hydrogels typically exhibit significant hysteresis during cyclic stretching-releasing process due to the presence of a sacrificial network. Consequently, it is a considerable challenge for designing hydrogels that are both low in hysteresis and high in toughness for applications requiring dynamic mechanical loads. Herein, the study introduced a novel "sliding tangle island" strategy for creating tough and low-hysteresis hydrogels, which are prepared through in situ polymerization of highly concentrated acrylamides (AM) to form numerous entanglements within the MXene spacing without any chemical crosslinker. The MXene entangled with long polyacrylamide (PAM) chains to form tangle island that served as a relay station to transmit stress to neighboring molecular chains. This mechanism helps alleviate stress concentration and enhances energy dissipation efficiency, thereby reducing mechanical hysteresis. The resulting hydrogel exhibited exceptional properties, including high stretchability (≈900%), low hysteresis (less than 7%), high toughness (1.34MJm-3), and excellent sensing performance to rival the commercial hydrogel electrode. Therefore, this work sheds light on feasible design of energy dissipation structure to reduce the hysteresis of the composite hydrogels.

Research on roof caving mechanism and influencing factors in inclined ore body caving mining

In the process of caving mining, the overlying strata often fall down to form a concealed goaf. The goaf of caving method is characterized by strong concealment, complex shape and unstable roof. The mathematical model of energy dissipation structure of goaf instability and caving is constructed, and the mechanism of goaf instability and caving is revealed from the perspective of energy. By establishing the joint coupling model of inclined ore bodies in metal mines, the development mechanism and influencing factors of roof caving arch along dip and strike are studied. The research shows that the roof surrounding rock of goaf has the characteristics of double arch of “stress - caving” when mining with inclined ore body caving method; The falling arch is basically symmetrical arch along the strike and asymmetrical arch along the dip, which is higher in the middle and upper part of the dip and lower in the lower part; The relationship between the maximum displacement of caving and the thickness of ore body is quadratic polynomial; The lower the dip angle of the ore body is, the larger the roof caving range is, but the smaller the maximum caving displacement is; The existence of hanging wall fault will affect the expansion path of roof caving, but make roof caving more sufficient.

Seismic behaviour of a steel moment resisting frame structure featuring hourglass double split tee joints

The occurrence of brittle fractures in welds of full-strength joints of steel moment-resisting frames (MRFs) during earthquakes in Northridge (1994) and Kobe (1995) marked a turning point in seismic design philosophies for steel structures. This led to the development of new strategies focusing on enhancing structural resilience and energy dissipation. While Reduced Beam Sections (RBS) were traditionally favoured, recent approaches include partial-strength joints and replaceable dissipative fuses, in some cases also equipped with self-centring components. These systems often employ friction or yielding dampers, ensuring that the weakest joint component comprises well-designed dampers for optimal ductility and energy dissipation.In this context, the present study evaluates the performance of a large-scale structure featuring MRFs with partial-strength double-split tee (DST) joints and hourglass dampers. These joints are conceptually similar to ADAS dampers and the Simpson Strong Tie moment connection prequalified by AISC 358–16. The research involves conducting a pseudo-dynamic test campaign on a two-storey steel structure designed according to EC8 provisions. Findings from experiments and a numerical model developed using OpenSees are discussed. Incremental Dynamic Analyses (IDAs) compare structures with hourglass DST joints to those with full-strength joints, showing enhanced self-centring capacity in DST-equipped structures despite lacking dedicated self-centring components. Additionally, structures with hourglass DST joints demonstrate significant low-cycle fatigue life, potentially reducing the need to replace dissipative components after severe seismic events.

Multi-objective optimization of energy-dissipating steel plate fuse links using response surface method

Steel plates with openings are used to provide energy dissipation in earthquake-resistant structures. Shear-acting steel plates with butterfly-shaped or straight links are particularly used as easily replaceable fuses in low-damage design of structures. Sensitivity analyses have shown that the cyclic response of steel plate fuses varies depending on the shape of the fuse link. However, simultaneous response optimization approaches have not been applied in the past research on steel plate fuses. A multiple-response optimization study is needed to find optimal link shapes with improved cyclic response characteristics while simultaneously considering different optimization objectives. In this study, experimentally validated finite element simulations and response surface methodology are used to predict the cyclic load-displacement response of steel plate fuses. The behavior of steel plate shear links is evaluated in terms of initial stiffness, yield strength, ultimate stiffness, effective damping, peak strength, and ductility. Predictive equations are derived and verified for each response characteristic in terms of three influential factors, including the length to end-width ratio (L/b), end-width to thickness ratio (b/t), and mid-width to end-width ratio (a/b) of shear links. The predictive equations are then employed to perform multi-objective optimization studies using a desirability approach. Four different optimization objectives are considered, such as the maximization of effective damping and ductility. Optimal ranges are determined for each factor. The results show that the energy dissipation, strength, and ductility of the fuse can be simultaneously maximized if using relatively thick and moderately long links (with b/t smaller than 6.6, L/b between 2.7 and 6, and a/b between 0.33 and 0.96). Optimal fuses links are those with an intermediate a/b between 0.37 and 0.89 and a small to moderate b/t between 3.0 and 6.6.

Damage evolution and failure mechanism of masonry walls under in-plane cyclic loading

Masonry structures often exhibit poor seismic performance during earthquakes owing to their low material strength, structural integrity, and ductility. To address the mechanism of in-plane damage and collapse of masonry walls subjected to earthquake ground motion, three full-size brick walls, one with structural columns and two without structural columns, were designed and constructed in this experimental study to quantitatively investigate the effect of structural columns on the seismic performance of masonry walls. Quasi-static tests of masonry walls subjected to cyclic lateral loading were conducted using electrohydraulic servo actuators. The in-plane damage evolution and failure mode of the masonry walls under lateral loading were investigated. A numerical model with a novel plastic damage constitutive model of masonry was established. The accuracy of this model and the calculation results were verified by comparing them with the crack development and mechanical property curves obtained from the experiments. Based on the numerical model, a parametric analysis was conducted to investigate the influence of critical factors, such as mortar strength, vertical load, and height-to-width ratio, on the seismic performance of masonry structures. The test results showed that structural columns can effectively improve the performance of masonry structures. Properly installed structural columns can improve the peak load-bearing capacity, ductility, and energy dissipation of masonry structures. The masonry damage constitutive model used in this study could simulate the damage to masonry wall specimens well and reflect the hysteretic curves of the specimens within an acceptable range of accuracy. Thus, it provides a valuable reference for physical experiments. An appropriate mortar strength and vertical compressive stress can effectively enhance the load-bearing capacity of masonry structures within a certain range. For structural column walls. Walls with mortar strengths (average compressive strength) of 12.5 MPa, 10 MPa, 7.5 MPa, and 5 MPa showed an increase in peak bearing capacity of 26.2 %, 23.9 %, 18.5 %, and 9.4 %, respectively, compared to walls with mortar strengths (average compressive strength) of 2.5 Mpa. The aspect ratio had a significant impact on the shear load-bearing capacity of the masonry walls. An increase in the aspect ratio led to a transition from shear failure to flexural failure and a subsequent decrease in shear load-bearing capacity. For masonry walls with structural columns, increasing the diameter of the longitudinal steel in the structural columns can enhance the load-bearing capacity of the masonry wall, resulting in a significant improvement in its overall performance.

Classification and Application Development of Hedge Energy Dissipators

At present, most of China's oilfield mining using high-pressure fracturing and other methods, in the oilfield mining and subsequent pipeline transport are accompanied by a large amount of pressure and energy, the mining and pipeline transport equipment to produce a lot of wear and tear and hazards, so it is necessary to install pressure reduction and dissipation device. In the past, most of the sudden expansion and contraction of the energy loss generated by the pressure reduction and energy dissipation device. After continuous research by scholars, it is proposed to use the energy dissipation of the fluid between the pressure reduction and energy dissipation device, which has a higher stability, and can improve the efficiency of its energy dissipation. In this paper, the classification and research on the classification of the sudden expansion and contraction energy dissipation structure, the classification, optimal design and the application development of the hedge type energy dissipation structure in the field of petroleum industry are discussed, and some outlooks and suggestions are put forward for the research and development of the hedge type energy dissipation device in the future.

Preliminary Discussion on the Current Sheet

The current sheet is a characteristic structure of magnetic energy dissipation during the magnetic reconnection process. So far, the width and depth of the current sheet are still indefinite. Here we investigate 64 current sheets observed by four telescopes from 1999 to 2022, and all of them have been well identified in the previous literature. In each current sheet, three width values are obtained at the quartering points. Based on these investigated cases, we obtain 192 values, which are in a wide range from hundreds to tens of thousands of kilometers. By calculating the pixel width (PW: the ratio of the current sheet width to the pixel resolution of corresponding observed data) of these current sheets, we find that more than 80% of the PW values concentrate on 2–4 pixels, indicating that the widths of the current sheets are dependent strongly on the instrument resolutions and all the sheets have no observable three-dimensional information. To interpret this result, we suggest that there are two probabilities. One is that the width of the current sheet is smaller than the instrument resolution, and the other is that the detected current sheet is only a small segment of the real one. Furthermore, there is another possible scenario. The so-called current sheet is just an emission-enhanced region.

ENERGETIC CONDITIONS OF MAXIMISING TEMPERATUREAND ENERGY DENSITY IN THE ENVIRONMENT OF FRICTIONCONTACT OF SOLIDS

The paper is intended to determine maximum temperatures in the friction zone of solids. An original model ofthermal processes in a miniature test object – environment of a selected contact of asperities – is proposed. Itsvolume is limited to an area where energy dissipation and wear take place. The discussion is based on an energybalance including temperature variations within the object. An original method of establishing the maximumvalue of the so-called flash temperature on the basis of an experiment addressing the thermodynamic natureof friction is proposed. A method of determining average density of energy dissipated in a tested volume isspecified as well. An analytical description of elementary friction includes physical properties of a material:density, specific heat, hardness; parameters characterising friction and wear, such as coefficient of friction,coefficient of wear, nominal unit pressure, specific work of wear, unit work of mechanical dissipation,temperature of friction surface, temperature of the immediate environment of surface asperities contact,mass of energy dissipation area, mass wear, and structure of the energy balance. The proposed description offriction within a contact of surface asperities encompasses analytical dependences that relate all the physicalquantities accepted as characteristics of an object and the process inside it to one another. A quantitativeevaluation of the maximum temperature and density of dissipated energy is undertaken for a selected instanceof tribological testing.

Laboratory data linking the reconfiguration of and drag on individual plants to the velocity structure and wave dissipation over a meadow of salt marsh plants under waves with and without current

Abstract. Salt marshes provide valuable ecosystem services, which are influenced by their interaction with currents and waves. On the one hand, currents and waves exert hydrodynamic forces on salt marsh plants, which shapes the distribution of species within the marsh. On the other hand, the resistance produced by the plants can shape the flow structure, turbulence intensity, and wave dissipation over the canopy. Because marsh plants are flexible structures, their reconfiguration modifies the drag felt by the plants and the flow. While several previous studies have considered the flexibility of the stem, few studies have considered the leaf component, which has been shown to contribute the majority of plant resistance. This paper reports a unique dataset that includes laboratory measurements of both the force on an individual plant and the flow structure and wave energy dissipation over a meadow of plants. In the individual plant experiment, the motion of the plant and plant drag, free-surface displacement, and velocity profile were measured. The individual plant experiments considered both a live marsh plant (Spartina alterniflora) and a mimic consisting of 10 leaves attached to a central stem. For the meadow experiment, velocity profiles were measured both upstream and within the meadow, and free-surface displacement was measured along the model marsh plant meadow with high spatial and temporal resolution. These experiments used five water depths (covering both submerged and emergent conditions), three wave periods (from long wave to short waves), seven wave heights (from linear to nonlinear waves), and six current conditions (including pure current, pure wave, and combined current and wave). In summary, there are 102 individual plant tests and 58 meadow tests. The drag, free-surface displacement, and velocity are reported in the SMCW.mat and SMCW.nc files including the raw data, the phase averages, and the statistical values. A link to the plant motion videos is also provided. This dataset provides high-quality measurements that can be used to develop and validate models of plant motion, hydrodynamic drag on individual plants, vegetation-generated turbulence, the evolution of flow structure through a meadow, and the transformation and dissipation of waves over natural salt marshes. The dataset is available from Figshare with detailed instructions for reuse (https://doi.org/10.6084/m9.figshare.24117144; Zhang and Nepf, 2023a).

Tough double network hydrogels with rapid self-reinforcement and low hysteresis based on highly entangled networks

Most tough hydrogels are reinforced by introducing energy dissipation mechanisms, but simultaneously realizing a high toughness and low hysteresis is challenging because the energy dissipation structure cannot recover rapidly. In this work, high mechanical performance highly entangled double network hydrogels without energy dissipation structure are fabricated, in which physical entanglements act as the primary effective crosslinking in the first network. This sliding entanglement structure allows the hydrogel network to form a highly uniform oriented structure during stretching, resulting in a high tensile strength of ~3 MPa, a fracture energy of 8340 J m−2 and a strain-stiffening capability of 47.5 in 90% water content. Moreover, almost 100% reversibility is obtained in this hydrogel via energy storage based on entropy loss. The highly entangled double network structure not only overcomes the typical trade-off between the high toughness and low hysteresis of hydrogels, but more importantly, it provides an insight into the application of entanglement structures in high-performance hydrogels.

Investigation on unstable flow characteristics and energy dissipation in Pelton turbine

The internal flow scale of a Pelton turbine is variable, and the interaction between the jet and the bucket has strong transient characteristics, resulting in an incomplete understanding of its internal vortex structure evolution and energy dissipation mechanisms. In order to reveal the influence of vortices on the flow regime and energy dissipation mechanisms in the turbine, this paper establishes the correlation between the unsteady flow characteristics and energy dissipation inside the Pelton turbine based on the energy balance equation and quantifies the energy losses inside the turbine. The results indicate that vortex structures present a non-uniform distribution inside the jet, which disrupts the uniformity of the jet velocity distribution, resulting in an uneven distribution of high-vorticity zones on the bucket surfaces and intensifying flow interference among the buckets. The strong shear flow caused by the downstream flow detachment of the needle guide, the turbulent boundary layer on the jet surface, and the wake effect downstream of the needle tip are the main reasons for the dissipation of fluid kinetic energy. The distribution range of energy loss on the rotating bucket closely corresponds to the position of the high-vorticity zone. Energy dissipation inside the turbine is primarily in the form of turbulent kinetic energy, and the injectors and runner are the primary energy dissipation components. Moreover, inside the injectors, each form of energy loss remains relatively constant, whereas inside the runner, its rotation induces fluctuating energy losses attributed to Reynolds stress work. The results contribute to an enhanced understanding of the energy dissipation characteristics and complex flow mechanisms within the turbine, providing reference for the optimisation and efficient operation of the multi-nozzle Pelton turbine.

An efficient nonlinear hybrid model of energy dissipation piers utilizing fiber beam and self-developed hysteretic spring elements

Energy dissipation piers comprised of concrete filled steel tubular (CFST) columns and steel shear links can exhibit good seismic performance by reasonable collaborative optimization design of columns and links. Considering the time and economic costs of experiments and fine element analysis (FEA), an efficient and accurate numerical model is critical to investigate the hysteretic behavior of energy dissipation piers under earthquake action. Therefore, a hysteretic constitutive law for steel shear links is first proposed including the theoretical shear force-deformation skeleton curve and the unloading and reloading rules during hysteretic loading. Next, a hysteretic spring model is developed for efficiently simulating the hysteretic mechanical behavior of steel shear links, which is validated to have good accuracy with comparison to fine FEA and experimental results. Then, a simplified hybrid model consisting of the self-developed spring model and fiber beam model and two multi-scale FEA models with different levels of refinement are established for nonlinear analysis of energy dissipation piers, respectively. The comparison of numerical and test results confirms that the innovative fiber beam-spring hybrid model can accurately describe the hysteretic performance of energy dissipation piers, especially the detailed mechanical behavior of steel shear links and column feet, which provides an efficient numerical tool for analysing the collaborative working mechanism of energy dissipation piers and similar energy dissipation structures.

Experimental and numerical investigation of austenitic stainless steel (304 type) slit damper structural behavior

Carbon steel dampers have been applied for the seismic retrofitting of new and existing building structures. Experimental and numerical studies on the seismic response characteristics and reinforcement effects of applying stainless steel for the seismic retrofitting of building structures were recently conducted in the United States and Europe. Owing to its superior corrosion resistance, durability, sustainability, and fire resistance compared to carbon steel, austenitic steel is widely used as a structural material. In this study, experiments and numerical analyzes were performed to investigate the structural behavior and energy dissipation capacity of austenitic stainless steel slit dampers. The material test results show that austenitic stainless steel (STS304) underwent noticeable strength enhancement after yielding under cyclic loading compared to steel under monotonic tensile loading. The ultimate strength of the specimens also tended to increase in each cycle due to the cyclic hardening effect. A finite element (FE) analysis model was developed to predict the hysteretic behaviors of stainless steel dampers based on the cyclic material test results. The validity of the FE analysis model was verified through comparison with the test results and stress and strain distribution on critical section were discussed. In addition, the hysteretic behavior of the single story frame with chevron brace and stainless steel slit damper was investigated and compared with that of carbon steel damper.

Multilayered Inhomogeneous Beams under Torsion and Bending: An Analytical Study of Energy Dissipation

The present theoretical paper is devoted to the problem of energy dissipation in multilayered inhomogeneous beam structures of visoelastic behaviour. In particular, our attention is concentrated on studying the energy dissipation for the case of a beam that is loaded simultaneously in torsion and bending. Both torsion and bending moments which are applied on the beam change with time so that the angles of twist and rotation of the beam end vary continuously with time. The viscoelastic mechanical behaviour of the beam under torsion is treated by a viscoelastic model that has two linear springs and a linear dashpot. The model is under time-dependent shear stress. The viscoelastic behaviour of the beam under bending is modelled in a similar way. An analytical approach of deriving the energy dissipation is applied. The approach treats a multilayered beam that has an arbitrary number of layers of different thicknesses and material properties. The layers are longitudinally inhomogeneous. An investigation of the energy dissipation is carried-out to clarify the effect of the parameters of the time-dependent bending and torsion moments, the material inhomogeneity and the beam size on the energy dissipation.

Dynamic principle analysis of reinforced concrete replaceable coupling beam energy dissipation structure

Reinforced concrete shear wall is one of the most common structures in tall buildings. As an effective means to control structural vibration response, energy dissipation damping is widely applied to reinforced concrete shear wall structures. Replaceable steel coupling beams (RSCB) is a new technology in the energy dissipation damping field, and are being gradually adopted by construction projects since their introduction. However, current research on RSCB damping performance and space optimization has some shortcomings. This paper discusses RSCB working principles based on structural dynamics theory and derives damping performance curves of corresponding structures, and a primary evaluation of seismic response method for RSCB structures is proposed. Finally, the energy dissipation performance of a typical reinforced concrete shear wall structure is analyzed based on performance curves and formula of structural dynamics constructed by this paper. Relevant outcomes of this paper will provide theoretical support and technical guidance for construction design and in-depth research of RSCB.

Seismic fragility analysis of rocking buckling-resistant braced structures subjected to far-field and near-field ground motions

To address the inadequate seismic performance of traditional buckling-restrained braced frame structures (BRBFS), this study introduces a novel structure, the rocking buckling-restrained braced frame structure (RBRBFS). The RBRBFS achieves effective control of main structure damage and enhances structural energy dissipation and seismic resilience by disconnecting the column feet from the foundation in the BRBFS and using friction energy dissipation devices as rocking column feet. This research aims to quantitatively assess the seismic performance and collapse safety margin of the new RBRBFS under different types of ground motions. To achieve this goal, two eight-story structures, one is traditional BRBFS and the other is RBRBFS, were designed. Incremental Dynamic Analysis (IDA) was employed, accounting for ground motion uncertainty, to conduct a comparative study of the seismic fragility of both structures subjected to near-fault pulse-like and far-field earthquake ground motions. Nonlinear dynamic analysis results indicate that under high-intensity ground motions, the RBRBFS significantly improves structural ductility and effectively controls structural damage. Compared to BRBF structures, the BRBFS exhibit a reduction of 26.5% and 18.3% in damage probability deviation under the two seismic excitations, highlighting their more stable structural response under varying seismic conditions. Furthermore, this novel RBRBFS increases the collapse margin ratio by 25% to 30%, demonstrating its higher seismic collapse resistance capacity

Seismic performance of improved multistorey X-braced steel frames

During an earthquake, the brace of a multistorey X-braced steel frame experiences out-of-plane instability. After the brace becomes unstable, the middle span of the brace-intersected beam exhibits a large imbalance force. This force causes a significant vertical displacement in the middle of the brace-intersected beam. To address this issue, an improved multistorey X-braced steel frame is proposed. Adding an arc energy-dissipation structure to the original structure adjusts the bearing capacity of the brace and ensures that the brace does not lose stability. The deformation of the arc energy-dissipation structure reduces the vertical displacement of the brace-intersected beam. A finite element model of the improved multistorey X-braced steel frame is established, and the seismic performance of the structure is analysed. The analysis shows that the brace of the improved multistorey X-braced steel frame does not experience instability, and the lateral bearing capacity is increased by 20%. The vertical displacement in the middle of the brace-intersected beam is small. The improved multistorey X-braced steel frame exhibits good seismic performance.

Seismic behavior and life-cycle cost effectiveness of steel moment resisting frame structures with self-centering friction-viscous dampers

The self-centering friction-viscous damper (SCFVD) is a novel self-centering system that utilizes preloaded ring springs to offer self-centering and friction-based energy dissipation capacity, while a viscous damper provides viscous-based energy dissipation capacity. This study is to study the seismic behavior of steel moment-resisting frames (MRFs) with SCFVDs, considering cost effectiveness. The mechanical model of the SCFVD is first presented and validated through pseudo-static tests on a full-scale specimen. Simulation models of 3-story, 9-story, and 20-story steel MRFs with SCFVDs and viscous dampers are then built, and numerical analysis under 40 earthquake records is conducted on them to compare and evaluate the structural peak dynamic response and energy dissipation from an economic perspective. The results show that the SCFVD's hysteretic response can be reliably predicted by the mechanical model. When compared to the uncontrolled steel-MRFs and the steel-MRFs with FVDs, the SCFVD can significantly mitigate structural peak and residual drift, especially under high-intensity earthquakes, but may aggravate structural peak acceleration. Besides, the SCFVD can mitigate the structural hysteretic energy dissipation and damage to the 3-story and 9-story steel MRFs. The cost/average reduction ratio of peak drift for the steel-MRFs with SCFVDs is reduced by 6.3% when compared to that for the steel-MRFs with FVDs.

Composite nanofillers with a locust-like cushioned half-moon structure to improve the impact resistance of polyurethane

Developing a highly impact absorption properties polyurethane elastomer with exceptional strength and toughness is crucial in the realm of polyurethane impact protection. Inspired by the energy dissipation structure of the soft and hard bonding in the hind limb of locusts, the paper fixed the dynamic disulphide bonds commonly found in bioproteins after hydroxy-functionalized on SiO2 by quaternization reaction, and is creatively applied in the field of impact resistance as soft and hard sacrifice micro-regions into the polyurethane. Benefiting from the multi-scale energy dissipation approach formed by the breakage of dynamic disulphide bonds, the stress obstruction by rigid particles, and the strong bonding interface between the composite filler and the matrix, polyurethane composite have demonstrated great efficiency in energy absorption and impact protection. The static compression strength of IPS@SiO2/PUE is 148.8% higher compared to neat PUE. Furthermore, the dynamic impact energy absorption of the composite PUE was increased by 109.36%, nearly twice that of the original polyurethane. This study proposes that this strategic approach has the potential to offer a novel method for material design, which facilitates bionic design of high-impact protective elastomers utilizing different energy dissipation mechanisms.
