This study is designed to examine the effect of pore size on the performance of aluminum matrix compo-sites reinforced with silicon carbide (SiC) particles that contain porosity. To accomplish this, we evaluate both constant and variable pore diameters, assuming a circular shape while preserving the same volume fraction. Finite element analysis is conducted on a square matrix reinforced with nine particles and subject-ed to a tensile test. The simulation utilizes a two-dimensional plane strain model, incorporating square, hexagonal, and random distributions of multiple particles. The findings reveal that, even with the existence of pores, the transfer of stress from the softer matrix to the reinforcement is still effective. Furthermore, it is observed that the composite's properties are increasingly influenced by porosity and pore size, especially as the pore diameter enlarges and the proximity to the particles diminishes.
