Background:: Particle Reinforced Metal Matrix Composites (PRMMCs) are widely used because of the higher specific strength, better dimensional stability, lower thermal expansion coefficient, better wear and corrosion resistance. However, the existence of reinforcing particles makes it hard to machine. The main manifestations are as follows: severe tool wear, easy generation of debris tumors in processing, and many defects on the machined surface, etc. These seriously limit its wider application. The Finite Element Method (FEM) has been widely applied in the research of PRMMCs machining according to recent patents, which can improve the efficiency and reduce the cost of research. Therefore, it is necessary to carry out a deep research for the processing technology of PRMMCs. Methods:: In this paper, the latest research progress of finite element simulation of cutting PRMMCs was summarized. The key technologies of finite element simulation, including constitutive model, geometric model, friction model between chip and tool, fracture criterion and mesh generation, are comprehensively analyzed and summarized. The application in the specific processing methods was discussed, such as turning, milling, grinding, ultrasonic vibration grinding and drilling. The existing problems and development direction of the simulation of PRMMCs cutting are also given. Besides, a lot of patents on finite element simulation for PRMMCs machining were studied. Results:: Finite element model for the actual composition determines the accuracy of finite element simulation. Through the secondary development of finite element software, a more realistic finite element model of Particle reinforced metal matrix composites can be established. Conclusion:: Finite Element Method (FEM) provides a new approach for the study of mechanism of Particle reinforced metal matrix composites machining. Quantitative analysis and prediction of micro- details in cutting can be realized.

The paper describes the results of a numerical study using Galerkin’s finite element method on an infinitely wide slider bearing. The analysis is based upon the generalized Reynolds equation with the assumption that the pressure gradient in the lubricating film is negligible in the axial direction. Detailed results for bearing characteristics including pressure, load capacity, frictional force, frictional coefficient as a function of film thickness ratio (aspect ratio), and velocity of slider show that these parameters have a strong influence on the bearing behavior. Specifically, it has been shown that friction coefficient and frictional force increases with lower aspect ratios. Also, higher load carrying and maximum pressure is obtained with increased speed of the slider Point wise comparison of the results obtained using the Finite Element Method and that obtained with second order Finite Difference marching Method using base parameters show that the latter simulation has a maximum point wise error of 0.46% in comparison to 0.32% for Finite Element simulation. It has been shown that the Finite Element Method produces more accurate results. The results are in tabular and graphical forms.

This paper presents a numerical method and computational results for acoustic noise of electromagnetic origin generated by an induction motor. The computation of noise incorporates three levels of numerical calculation steps, combining both the finite element method and boundary element method. The role of magnetic forces in the production of acoustic noise is established in the paper by showing the magneto-mechanical and vibro-acoustic pathway of energy. The conversion of electrical energy into acoustic energy in an electrical motor through electromagnetic, mechanical, or acoustic platforms is illustrated through numerical computations of magnetic forces, mechanical deformation, and acoustic noise. The magnetic forces were computed through 2D electromagnetic finite element simulation, and the deformation of the stator due to these forces was calculated using 3D structural finite element simulation. Finally, boundary element-based computation was employed to calculate the sound pressure and sound power level in decibels. The use of the boundary element method instead of the finite element method in acoustic computation reduces the computational cost because, unlike finite element analysis, the boundary element approach does not require heavy meshing to model the air surrounding the motor.

The Future

The behaviour of granular materials especially under dynamic loading has been under investigation for years. In recent years, the advancing computer technology makes it possible to model complicate behaviour under different loadings. In this review paper, major advances and researches in the field of providing conceptual model for behaviour of granular materials have been reviewed. The reviewers have tried to categorise the researches in term of their approach to modelling the mechanical behaviour of granular materials and then identify the gaps to provide ground for the future researches.
