摘　　要：用一级压缩气体炮加载技术和可变平板电容传感技术，对不锈钢（００Ｃｒ１８Ｎｉ９） 动态累积损伤进行了实验研究，给出了层裂累积损伤连续度量的经验关系式，并对损伤度与动载历史的相互关系进行分析、讨论。Studies on the dynamic accumulation damage for the stainless steel(00Cr18Ni9) have been performed with a compressed gas gun and a capacitor gauge technique.The continuously measuring empirical expressions for the damage accumulation are given,the relation between the dynamic damage level and the stress history are also discussed.

关 键 词：累积损伤 损伤速率函数 层裂 不锈钢
