利用二维弹塑性流拉格朗日—欧拉混合法数值模拟程序模拟了飞片撞击PBX-9404炸药的物理过程,获得了3种爆轰现象,并提供了有关撞击起爆过程中飞片面积和压力对起爆效果影响的结论。
The two-dimensional elastoplastic Lagrangian-Eulerian hybrid simulation method was used to simulate the physical process of the fly-by-bomb impact on the PBX-9404 explosive. Three kinds of detonation were obtained and the relation between the area of the fly- And pressure on the detonating effect of the conclusion.
