Numerical simulation of the forming process of the fin?adhered EFP was carried out with the ALE method using LS?DYNA. The result indicates that such a charge structure can form EFP with eight fins,the length?diameter ratio of EFP with fins is 2.23 times than that of EFP without fins,and velocity increases by 15 percent.
