对由两个随机分布的线弹性相组成的异质材料的整体机械响应以及应变和应力场统计进行了数值研究。球体的布尔模型用于生成由多孔或刚性夹杂物组成的微结构，无论相的体积分数如何。计算应力和应变场积分范围或等效的代表性体积元素并将其与场统计特征以及微观结构几何形状相关联。
The overall mechanical response as well as strain and stress field statistics of an heterogeneous material made of two randomly distributed, linear elastic phases, are investigated numerically. The Boolean model of spheres is used to generate microstructures consisting of either porous or rigid inclusions, at any volume fraction of the phases. Stress and strain field integral ranges, or equivalently the representative volume element, are computed and linked to features of the field statistics, and to the microstructure geometry.
