Abstract: | A three-dimensional model based on the generalized method of cells (GMC) principle has been used to predict the effective
properties of particulate-reinforced metal matrix composites (PMMCs). The effects of constituent phases on the elastic properties
of PMMCs are predicted using GMC. The predictions are compared with an assortment of finite-element predictions and experimental
results available in the literature. The accuracy and the computational efficiency of the GMC model are also discussed. Moreover,
the effect of particle shape and orientation on the elastic properties of PMMCs has been predicted and analyzed. Cubical and
parallelepiped shaped particles having different orientations are considered for this study. Significant variations are noted
on the elastic properties of the PMMC systems by altering the shape and orientation of the particles. |
