A comprehensive review of experimental studies on shear behavior of bolted rock joints with varying rock joint and bolt parameters and normal stress

AbstractThe shear characteristics of bolted rock joints are crucial for the stability of tunneling and mining, particularly in deep underground engineering, where rock bolt materials are exposed to high stress, water pressure, and engineering disturbance. However, due to the complex interaction between bolted rock joints and various geological contexts, many challenges and unsolved problems arise. Therefore, more investigation is needed to understand the shear performance of bolted joints in the field of deep underground engineering. This study presents a comprehensive review of research findings on the responses of bolted joints subjected to shearing under different conditions. As is revealed, the average shear strength of bolted rock joints increases linearly with the normal stress and increases with the compressive strength of rock until it reaches a stable value. The joint roughness coefficient (JRC) affects the contact area, friction force, shear strength, bending angle, and axial force of bolted rock joints. A mathematical function is proposed to model the relationship between JRC, normal load, and shear strength. The normal stress level also influences the deformation model, load‐carrying capacity, and energy absorption ratio of bolts within bolted rock joints, and can be effectively characterized by a two‐phase exponential equation. Additionally, the angle of the bolts affects the ratio of tensile and shear strength of the bolts, as well as the mechanical behavior of both bolted rock joints and surrounding rock, which favors smaller angles. This comprehensive review of experimental data on the shear behavior of bolted rock joints offers valuable theoretical insights for the development of advanced shear devices and further pertinent investigations.

Mitophagy, Inflammasomes and Their Interaction in Kidney Diseases: A Comprehensive Review of Experimental Studies.

Mitophagy is an important mechanism for mitochondrial quality control by regulating autophagosome-specific phagocytosis, degradation and clearance of damaged mitochondria, and involved in cell damage and diseases. Inflammasomes are important inflammation-related factors newly discovered in recent years, which are involved in cell innate immunity and inflammatory response, and play an important role in kidney diseases. Based on the current studies, we reviewed the progress of mitophagy, inflammasomes and their interaction in kidney diseases.

A review of experimental studies on the proppant settling in hydraulic fractures

The hike of hydraulic fracturing in North America and beyond leads to significantly enhanced hydrocarbon production especially in low-permeability geological formations. Proppant settling is one of the most important particle motions during a hydraulic fracturing process, which to a large extent determines the created fracture's conductivity. This paper provides a critical review of the proppant settling in hydraulic fractures, with an emphasis on the experimental studies published in the past several decades. Six factors are identified out of a proppant/fracturing-fluid/fracture system: wall retardation, fluid rheology, proppant non-uniformity, proppant surface wettability, proppant concentration, and fracture complexity. Influences of these factors on the proppant settling are summarized based on the analysis of published experimental data, images, and correlations. Notwithstanding the extensive experimental studies, more experiments are in demand to systematically investigate proppant settling behavior in various kinds of fracturing fluids confined by hydraulic fractures. In addition, a gap is found to exist between the experimental studies of proppant transport and the application of the experimental findings to numerical simulations of hydraulic fracturing. • We conduct a comprehensive review of experimental studies on proppant settling in hydraulic fractures. • Six influential factors on proppant settling are identified. • More experiments are needed to study proppant settling behavior in non-Newtonian fracturing fluids. • More work is needed to properly apply experimental findings to numerical simulations and field operations.

Hypervelocity Impacts on Satellite Sandwich Structures—A Review of Experimental Findings and Predictive Models

Sandwich panels are widely used in the design of unmanned satellites and, in addition to having a structural function, can often serve as shielding, protecting the satellites’ equipment from hypervelocity impacts (HVI) of orbital debris and micrometeoroids. This paper provides a comprehensive review of experimental studies in the field of HVI on sandwich panels with honeycomb- and open-cell foam cores, as well as an examination of available predictive models for the assessment of the panels’ ballistic limits. The emphasis of the review is placed on: (i) identifying gaps in the existing experimental database and the appropriate directions for its further expansion; and (ii) understanding the limitations of the available predictive models and the potential for their improvement.

Formation of advanced glycation endproducts in foods during cooking process and underlying mechanisms: a comprehensive review of experimental studies.

Advanced glycation endproducts (AGE) are a group of complex and heterogeneous molecules, sharing some common characteristics such as covalent cross-link formation among proteins, the effect of transforming the colour of food products into yellow-brown colours and fluorescence formation. AGE are linked to many diseases including diabetes, renal diseases, CVD, liver diseases, neuro-degenerative and eye disorders, female reproductive dysfunction, and even cancer. AGE are formed endogenously but are also provided from exogenous sources including diet and tobacco. Western diet, rich in processed and/or heat-treated foods, fat and sugar, increases the exposure to AGE. The foods that contain high levels of fat and protein are generally rich in terms of AGE, and are also prone to AGE formation during cooking compared with carbohydrate-rich foods such as vegetables, fruits, legumes and whole grains. The present article aimed to review the literature about the effects of different cooking methods and conditions on the AGE content of food and AGE formation mechanisms using a comprehensive approach.

Residual Capacity of Corroded Reinforced Concrete Bridge Components: State-of-the-Art Review

The current paper provides a comprehensive review of experimental studies on corrosion damaged reinforced concrete (RC) components, and the ability of current state-of-the-art numerical models to predict the residual capacity of these corroded RC components. The experimental studies on corroded RC components are classified into five different categories including: (i) beams in flexure, (ii) beams in shear, (iii) columns under pure axial compression, (iv) circular columns in flexure, and (v) rectangular columns in flexure. For each group, a summary of all the previous research are provided. Through the regression analyses, the experimental results of each abovementioned groups are used to examine the adverse effect of corrosion on ductility and, flexural, shear, and axial capacity loss of the corroded RC components. Finally, the observed results of the previous experimental studies are compared with the predicted values using the state-of-the-art numerical models currently available in the literature. The summarised experimental results show that corrosion has much more adverse impact on ductility of the RC columns than strength. However, the effect of corrosion on ductility and strength reduction of RC beams is the same. Moreover, results of cross-sectional moment-curvature analyses using the state-of-the-art corrosion damage models show a good correlation between the predicted residual flexural capacity and observed experimental results. Finally, the existing shortcomings in the literature and open issues to be addressed in the future research are discussed, and some recommendations are provided.
