Study on damage mechanism and damage distribution of the rear plate under impact of debris cloud
《Defence Technology（防务技术）》2024年第5期151-167,共17页Chenyang Wu Xiaowei Chen Qiguang He 
supported by the Innovative Research Groups of the National Natural Science Foundation of China(Grant No.12221002)。
The debris cloud generated by the hypervelocity impact(HVI)of orbiting space debris directly threatens the spacecraft.A full understanding of the damage mechanism of rear plate is useful for the optimal design of prot...
