Study on the Influence of Amplitude on Ultrasonic Assisted Grinding of Hard and Brittle Materials

With the development of advanced manufacturing technology, ceramic matrix composite materials, a typically hard and brittle material, have been widely used in high-tech fields such as aerospace manufacturing. Due to the anisotropy of materials, the quality of conventional processing workpieces is poor, and the processing accuracy is difficult to guarantee. In this experiment, ceramic matrix composite materials are machined by ultrasonic vibration grinding with the CBN grinding rods. The influence of amplitude on the grinding force and the surface quality of the workpiece in the grinding process are analyzed by a series of experiments on ceramic matrix composites. The results show that, compared with the conventional grinding process, in the ultrasonic vibration-assisted grinding process, the grinding force is reduced by about 60%, and the surface quality is also improved significantly,the surface roughness Sa is reduced by about 25%.

Peridynamic modelling of higher order functionally graded plates

With the development of advanced manufacturing technologies, the importance of functionally graded materials is growing as they are advantageous over widely used traditional composites. In this paper, we present a novel peridynamic model for higher order functional graded plates for various thicknesses. Moreover, the formulation eliminates the usage of shear correction factors. Euler–Lagrange equations and Taylor’s expansion are utilised to derive the governing equations. The capability of the developed peridynamic model is demonstrated by considering several benchmark problems. In these benchmark cases simply supported, clamped and mixed boundary conditions are also tested. The peridynamic results are also verified by their finite element analysis counterparts. According to the comparison, peridynamic and finite element analysis results agree very well with each other.

Computationally Efficient Approximations Using Adaptive Weighting Coefficients for Solving Structural Optimization Problems

With rapid development of advanced manufacturing technologies and high demands for innovative lightweight constructions to mitigate the environmental and economic impacts, design optimization has attracted increasing attention in many engineering subjects, such as civil, structural, aerospace, automotive, and energy engineering. For nonconvex nonlinear constrained optimization problems with continuous variables, evaluations of the fitness and constraint functions by means of finite element simulations can be extremely expensive. To address this problem by algorithms with sufficient accuracy as well as less computational cost, an extended multipoint approximation method (EMAM) and an adaptive weighting-coefficient strategy are proposed to efficiently seek the optimum by the integration of metamodels with sequential quadratic programming (SQP). The developed EMAM stems from the principle of the polynomial approximation and assimilates the advantages of Taylor’s expansion for improving the suboptimal continuous solution. Results demonstrate the superiority of the proposed EMAM over other evolutionary algorithms (e.g., particle swarm optimization technique, firefly algorithm, genetic algorithm, metaheuristic methods, and other metamodeling techniques) in terms of the computational efficiency and accuracy by four well-established engineering problems. The developed EMAM reduces the number of simulations during the design phase and provides wealth of information for designers to effectively tailor the parameters for optimal solutions with computational efficiency in the simulation-based engineering optimization problems.

Moreover, there is no need to use a shear correction factor. Euler-Lagrange equations and Taylor's expansion are utilised to derive the governing equations. Several benchmark problems are studied to validate the newly developed higher order functionally graded beam formulation by considering different boundary conditions including clamped, simply supported and mixed boundary conditions. Peridynamic results are compared against finite element analysis results. According to the comparison, peridynamic and finite element analysis results agree very well with each other.

Highly Conductive Graphene Electronics by Inkjet Printing

Graphene is currently emerging as an alternative to traditional conductive materials, such as copper and silver because of its excellent electrical conductivity and earth's carbon abundance. Graphene can be applied in many different electronic fields with different manufacturing methods to meet their specific requirements, which promote the development of advanced manufacturing technology in graphene electrical applications. Inkjet printing, as an environmentally friendly, low-cost and simple-to-operate advanced manufacturing method, has broad development prospects especially in the field of flexible electronics. In this review, several factors affecting the electrical conduction property of graphene applications in the inkjet-printed graphene process are listed as follows: the preparation method of ink, material and treatment of substrate, thickness of print, and annealing, especially whether a coffee ring is produced. In addition, this paper also cites some examples of inkjet-printed graphene in electrical conductivity. In order to continuously improve the procedure designs of graphene electronics fabrication, more accurate relationships between electrical conductivity of graphene and these parameters can be built. Based on the excellent prospect of inkjet printing technology in the field of conductive electronics, there will be some further research about the perfect implementation of graphene’s electrical conductivity.

A tool vector control for laser additive manufacturing in five-axis configuration

Laser additive manufacturing facilitates the manufacture of functional structures, gradient materials, and complex inner structure parts. This process, which is known for its rapid and green manufacturing capabilities, presents an important direction for the development of advanced manufacturing technologies. However, contour accuracy introduces a technical bottleneck that remains unsolved. In five-axis laser additive manufacturing, tool vector control plays a pivotal role in determining contour accuracy. Accordingly, this article proposes a method for tool vector control in five-axis laser additive manufacturing. This method utilizes a five-axis spiral milling tool path to change the vector direction for five-axis laser additive manufacturing and to improve the contour precision of complex surface parts. First, the continuous spiral tool path is obtained by using commercial CAM software. Second, based on the relationship between the additive and subtractive control vectors, the control vector of the obtained spiral tool path is converted into the tool vector control of the laser cladding. Third, the tool position point and tool vector are converted into a G code program via post processing. Fourth, the performance of the proposed method is verified by conducting a virtual simulation and a five-axis laser cladding experiment with a blade specimen.

Development of designing lightweight composites and structures for tailorable thermal expansion

Thermal expansion coefficient is an important parameter of thermal physical properties. Materials with zero thermal expansion (ZTE) are urgently needed in engineering applications, particularly in aerospace, precision instruments, and civil engineering, where the control of thermally induced expansion and stress over a wide range of temperatures is of significance. On the other hand, thermal expansion compensation requires materials to possess negative thermal expansion (NTE) and even a desirable positive thermal expansion (PTE). For example, thermal expansion modulation can be achieved via composites with an appropriate ratio of NTE inclusions and PTE substrates. In general, engineering applications have a serious need for materials and structures with tailorable CTEs. Hence, development of material with tailorable thermal expansion is of important scientific significance and engineering applications. At present, the available range of CTE in engineering materials is quite narrow. To obtain wide range of CTE, most of current researches are mainly concentrated on bulk materials and composites. Specifically, few bulk materials with low and negative CTEs have been reported. FeNi-based Invar alloysexhibit low CTEs because of the magneto-volume effect which, however, only exists under the Curie temperature (about 100°C). A family of ceramics with isotropic NTE and metal oxides with anisotropic NTEs, has been widely studied. Unfortunately, the inherent brittleness and low fracture toughness of the NTE ceramics restrict their usage in load-bearing applications. Fiber-reinforced composites are capable of providing tailorable CTEs because some fibers, such as carbon and graphite fibers, possess negative axial CTEs. However, largely different CTEs between the fiber and the matrix always result in matrix cracking under large temperature variation. Besides, through topology optimization of the three-phase composites, ZTE and the maximum uniaxial/biaxial stiffness characteristics can be obtained. However, the optimized geometries are still too complex for practical manufacture and engineering applications. It is important to integrate tailorable CTE with lightweight and robust mechanical properties for the materials. Lightweight composites attract intensive studies by virtue of their low density, excellent mechanical properties as well as tailorable thermal expansion coefficient. This paper firstly summarizes the significant engineering applications of thermal expansion controlling as well as the bulk materials with low and negative thermal expansion. Moreover, research achievements of the laminate, particle reinforced and topologically optimal composites with tailorable thermal expansion are detailly introduced. Finally, we present the latest research progress including geometry design methods, mechanisms, fabrication process and experimental characterization of tailorable thermal expansion for lightweight lattice composites. The design of lattice materials which are assembled through dual-material members, and honeycomb-like hybrid lattices which are composed of inner triangle and outside honeycomb initiates the macro scale lightweight lattice composites for tailorable CTE. However, the lattice composites with bending-dominated members display less stiffness compared with stretch-dominated lattices. Moreover, the complicated geometrical connections of the members lead to manufacture complexity. Triangle lattice composite exhibits tailorable CTE and are used as the basic unit to construct other lattice configurations such as the near zero thermal expansion lattice structures. Thus, numerous studies find the planar lattices and structures design based on this unit. With the development of advanced manufacturing technology, the study of the lightweight lattice composites will be promoted more deeply.

Issues confronted with biomaterials research and development and market access in craniomaxillofacial field

There are a variety of biomedical materials applied in craniomaxillofacial and dental clinical practice, plastic surgery, otorhinolaryngology and neurosurgery. With the increasing investment for the biomedical materials study, considerable progress has been obtained in biomaterials research. But overall, the field of biomaterials in China is still in a backward state. The development of advanced manufacturing technology has put forward new demands for the research of biological materials and has expanded the application, but at present, there are few biomaterials that meet the requirements. The further development of three-dimensional printing technology is beneficial to the preparation of the craniofacial personalized prosthesis, but biomaterials and instruments for clinical use must be accorded with corresponding regulation. To carry out clinical trials, the application must be submited to the Food and Drug Administration Department of the State Council for registration.

Electroforming Applied to Manufacturing of Microcomponents

Nowadays, there is an increased demand for micro-products and micro-components in many industry sectors therefore development of advanced manufacturing technologies and metrological instrumentation in this range, have thus become a critical issue and an engineering challenge. If a product cannot be measured, although it might be manufactured, it would not be possible to analyse its design in order to improve its functionality.
