中文摘要：

根据Eshelby提出的均匀弹性体椭球夹杂区域内外点的应变场思想,考虑复合材料中嵌入基体的任意两球形颗粒之间直接相互作用对复合材料等效特性的影响,提出预测功能梯度材料等效材料特性的细观力学方法,并在组分材料含量相近区域引入过渡函数。

英文摘要：

Based on the effective inclusion method and the idea of strain field inside-outside ellipsoid area proposed by Eshelby, a micromechanics method considering the interactions between particles used to predict mechanical properties of functionally graded materials is proposed in the paper. Comparing with the results predicted by Mori-Tanaka method, the results of the Functionally Graded Materials effective material properties obtained from the method proposed in this paper are better.
