This paper presents a finite element–based homogenization study to evaluate the effective elastic properties of an aluminum–silicon carbide (Al–SiC) particulate composite. A three-dimensional representative volume element (RVE) containing randomly distributed spherical SiC particles is analyzed using the SimScale platform. Under uniaxial loading conditions, the composite exhibits an effective Young’s modulus of 74 GPa, with an average axial stress of 73.16 MPa corresponding to an average strain of 9.88 × 10⁻⁴. The resulting elastic properties, stress, strain, and displacement fields are extracted and discussed in detail. Furthermore, the numerical results are compared with predictions obtained from the Tanaka micromechanical model, showing good agreement and confirming the validity of the proposed FEM-based RVE approach.References
