Meeting Location of Fragment and Shock Wave from Blast Fragmentation Warhead

In order to study the meeting location of fragments and shock waves after fragmentation warhead explosions, ANSYS/LS-DYNA was first used to numerically calculate the explosion process of the fragmented warhead, and then the location where fragments meet shock wave was experimentally determined, validating the numerical method.On the basis of above results, the influence of k, m, Q_V and Q_T on the meeting location was analyzed.The results show that the meeting location decreases with the increase of k, m, Q_V and Q_T.More precisely, the k increases by 31%, the distance between the meeting position and the explosion center decreases by 11.5%, the m is doubled, and the distance between the meeting position and the explosion center is reduced by 2.4%.
