摘　　要：利用非线性有限元程序LS-DYNA中的ALE算法对EFP的成型、冲击引爆带壳炸药作用过程进行了数值模拟.与试验结果相比较,数值模拟结果具有较高的可信度,证明采用了LS-DYNA中的ALE算法,能有效获取EFP对带壳炸药引爆过程的参数.The method of ALE arithmetics of LS-DYNA was used to simulate the formation process and the initiation process of shelled explosive of EFP （Explosively Formed Projectile）. The Numer ical simulation results are creditable and are in agreement well with that of the corresponding experiments. The investigation results show that the parameters of shelled explosive initiated by EFP can be got exactly by using ALE arithmetics of LS-DYNA.
