Effect of change of sand properties on travel distance of ricocheted debris
《Defence Technology（防务技术）》2021年第4期1486-1495,共10页Yoon Keon Kim Woo Chun Choi 
This study was financially supported by the Foundation Research Program[grant number UD170027GD]of the Agency for Defense Development and the Defense Acquisition Program Administration of the Republic of Korea.
The debris from exploded buildings can ricochet after colliding with the ground,thus increasing the debris travel distance and danger from any associated impacts or collisions.To reduce this danger,the travel distance...

Investigation on the spatial distribution characteristics of behind-armor debris formed by the perforation of EFP through steel target被引量：6
《Defence Technology（防务技术）》2020年第1期119-135,共17页Xin Wang Jianwei Jiang Shengjie Sun Jianbing Men Shuyou Wang 
supported by National Natural Science Foundation of China(Grant no.11872123)。
The behind-armor debris(BAD) formed by the perforation of an EFP is the main damage factor for the secondary destruction to the behind-armor components.Aiming at investigating the BAD caused by EFP,flash X-ray radiogr...
