基于复合球体组合模型，准确分析了由有限变形弹性基体和球形夹杂物或空隙组成的复合材料和多孔介质的各向同性大变形问题。对于多孔介质，膨胀和收缩的应力应变关系根本不同。结果表明，极少量的孔隙对膨胀有显着影响，但对收缩影响不大。
The problem of large isotropic deformation of composite materials and porous media consisting of a finitely-deforming elastic matrix and spherical inclusions or voids is analyzed exactly on the basis of the composite spheres assemblage model. For porous media, the stress strain relations for expansion and contraction are found to be fundamentally different. It is shown that a very small amount of pores has significant effect on expansion, but not on contraction.
