Abstract
The effective material properties of functionally graded materials are predicted using a modified Mori–Tanaka and a self-consistent method. The proposed micromechanics model accounts for both multi-phase heterogeneity and a number of layers. The influence of geometries and distinct elastic material properties of each constituent and voids on the effective elastic properties of FGM is investigated. Numerical examples of different functionally graded materials are presented. The predicted elastic properties obtained from the current model agree well with experimental results from the literature.
