In this paper, the effect of particle geometry on Young’s modulus for particulate-reinforced composites was estimated using finite elements analysis (FEA) and modified Halpin–Tsai (HT) equations, including not only the effect of the aspect ratio but also the particle shape. This modified HT model includes a new parameter (a) which depends on the angle of the particle corners. FEA was used as a starting point to find the composites behavior depending on the reinforcement features, results that were compared to experimental values. Young’s moduli and stresses distribution were estimated using an AlA356/SiC(p) composite as starting material . Selected particle geometries for modeling were cylinders, truncated cylinders, double cones, and double-truncated cones; while aspect ratios were modified from 0.6 to 1.8. There was an excellent agreement between experimental results, FEA, and modified Halpin–Tsai estimations, showing that the predicting ability of the Halpin–Tsai model could be improved by introducing different shape parameters.
