Double casing warhead with sandwiched charge:The axial distribution of fragments velocities
《Defence Technology（防务技术）》2024年第4期201-216,共16页Ping Ye Yongxiang Dong Qitian Sun Peizhuo Shi Wang Yao Yongnan Li Yujing Li Mingze Li 
supported by the National Natural Science Foundation of China(Grant No.11872121)。
The double casing warhead with sandwiched charge is a novel fragmentation warhead that can produce two groups of fragments with different velocity,and the previous work has presented a calculation formula to determine...

Fragment spatial distribution of prismatic casing under internal explosive loading被引量：4
《Defence Technology（防务技术）》2020年第4期910-921,共12页Tianbao Ma Xinwei Shi Jian Li Jianguo Ning 
supported by the National Natural Science Foundation of China(Grant No.11822203and 11702026)。
Non-cylindrical casings filled with explosives have undergone rapid development in warhead design and explosion control.The fragment spatial distribution of prismatic casings is more complex than that of traditional c...

Deformation,fragmentation and acceleration of a controlled fragmentation charge casing被引量：1
《Defence Technology（防务技术）》2019年第5期786-795,共10页Andreas Helte Olof Andersson Patrik Lundberg 
funded by the Swedish Armed Forces under Grant No AF.9220616
Two different finite element software,LS-DYNA and Impetus,have been evaluated to test their ability to predict the deformation,fragmentation and acceleration of a controlled fragmentation charge casing.The general-pur...

On the continued acceleration of bomb casing fragments following casing fracture被引量：4
《Defence Technology（防务技术）》2014年第2期211-218,共8页Michael D.HUTCHINSON David W.PRICE 
sponsored by the NWIPT Department of the U.K.Ministry of Defence
It has been said that,once a bomb casing has fractured, "detonation gases will then stream around the fragments or bypass them,and the acceleration process stops there." However,while apparently copious gas flow throu...
