摘要
对４５钢进行了层裂实验，对软回收试件进行了显微金相观测，观察了材料中微损伤的形核、增和聚合机制。将文献［３］中的动态损伤模型编入一维Ｌａｇｒａｎｇｅ有限差分动力学程序，对层裂实验进行了数值模拟，计算结果与实验吻合较好。
Spallation tests for mild steel 4 5 is performed;The mechanism of the nucleation,growth and coalescence of voids is observed by microscopic observation on the softly recoveredspecimen. The model presented in[3] is incorporated with a hydredynamic one-dimensional fi-nite-difference computer code,to simulate the process of spallation of 45 steel.Comparison of cal-culations with recorded data is fairly in good accord.
