摘要: 采用体胞模型的分析方法推导了材料在弹塑性变形阶段的孔洞增长方程。假设所有孔洞的内外半径之比相同，用数值方法定性分析了材料在层裂损伤过程中孔洞数密度分布的变化。通过分析孔洞数密度分布、孔洞体积累积百分比、不同大小孔洞所占体积份额的计算结果，指出初始损伤对损伤演化有直接影响。

Abstract: A void growth equation is derived for elastic-plastic deformation process by means of representative volume element (RVE). The distribution of the void number density has been numerically investigated under the condition of the same ratio of inner and outer diameters for all voids. Influences of initial damage on development of spalling damage have been indicated by analyzing the distribution of void number density, the cumulative percentage of void volume and the volume fraction of the different-seize voids.
