In this paper, statistical continuum mechanics modeling is applied to predict the elastic mechanical properties of an anisotropic Al‐SiC composite. Two‐point statistics are measured on vertical metallographic planes in three‐dimensional microstructures. As a result of anisotropy the correlation functions are orientation dependent. Longitudinal and transverse elastic moduli are calculated for two samples with different PSR and clustering, and the results are compared with upper and lower bound and experimental data. It’s observed that the theoretical results are in good agreement with experimental data and two‐point statistics significantly contribute to the estimation of the elastic modulus.read more
