The traditional analytical homogenization technique, which has been refined over the past century, seeks to elucidate the behavior of heterogeneous materials at a macroscopic level. Numerous factors impact the composite, including the types, sizes, positions, and shapes of the reinforcing materials. The morphology of particles has garnered significant attention in the field of particulate composites; smaller particles exhibit a strong adhesion to the matrix, resulting in a pronounced reinforcing effect. This research examines the elastic properties of 6061 aluminum alloy reinforced with SiC particles. The microstructures are discretized using 4-node quadrilateral membrane finite elements (PFR4M) based on the Plane Fiber Rotation (PFR) formulation. Virtual microstructure images were used to assess the elastic characteristics under unidirectional tensile loading. A parametric study was conducted to investigate the impact of microstructural factors, including particle orientation and shape (square, circular, rhombic, and ellipsoidal). Finally, the validation of the numerical homogenization results was carried out by comparing them with the Voigt–Reuss (VR) bounds and available experimental data, showing good agreement and confirming the reliability of the adopted numerical approach.
