| Abstract: | The method of ALE arithmetics of LSDYNA was used to simulate the formation process and the initiation process of shelled explosive of EFP(Explosively Formed Projectile).The Numerical 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. |
