采用圆柱基体包含球状空洞的体胞模型，设本构方程中含有二相粒子引起体积变化的体积分数，应用有限元方法研究了空洞的扩展规律以及整个体胞宏观力学参数的变化规律，证实了二相粒子的影响作用。
By using the cell model with spherical cavity containing cylindrical matrix, the constitutive equation contains the volume fraction of two-phase particles which caused by volume change. The law of cavity expansion and the variation law of macroscopic mechanical parameters of the whole cell were studied by finite element method. The effect of two-phase particles.
