Evaluation of Mechanical and Thermal Behaviour of Particle-Reinforced Metal Matrix Composite Using Representative Volume Element Approach

摘要

In this present work, material properties (Young's modulus and thermal conductivity) of Silicon Carbide (SiC) particle-reinforced Aluminium 1100 (Al) matrix composite have been evaluated using Representative Volume Element (RVE) technique. A three-dimensional RVE model is generated by finite element-based homogenization method for Al-SiC composite. SiC particles are randomly dispersed in various volume portions in the range of 5-20% into the matrix. Examinations are done to ponder the impact of spherical particle geometry on the material properties for all volume fractions using numerical analysis. The numerical results from the RVE approach are compared with the values obtained from the experimental results, rule of mixtures (ROM) and Halpin-Tsai equations and found that the results of RVE approach are in good agreement with the other approaches.
