Abstract

Abstract

According to the analysis of the tandem warhead characteristics, we proposed a new tandem shaped charge structure composed of two explosively-formed projectile charges with the same structure.By using the finite element software LS-DYNA, the effect of different explosion-proof bodies and different delay control on the forming process of the postpositive EFP charge were analyzed.Based on the above results, we conducted experiments for tandem EFP penetration with different delay time.The experimental results show that the penetration depth of the optimized tandem EFP charge can reach 96.7 percent of the sum depth that penetrated by a single EFP charge at twice.The penetration ability of the postpositive EFP charge is greatly improved.
