Standard test method for carbon black - void volume 炭黑压缩容积指数的标准试验方法
2.
The damage evolution law obtained from the model is related to the void volume fraction , the void shape , as well as triaxiality stress 进而采用hill自治方法，得到了珠光体材料宏观损伤本构描述，并发展了相应的数值方法与程序。
3.
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 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。
