  • In order to solve the problem about fast perforation of hunk fraise with enough depth and width, a new tandem shaped charge structure is proposed, which is composed of two same structure of EFP (explosively formed projectile) shaped charge.Using finite element software LS-DYNA3D, the forming process of this new structure and the effect of delay time on the forming process of tandem EFP are simulated and analyzed.On this basis, an experiment for tandem EFP penetrating 45 steel target is conducted.The results show that the tandem EFP charge can make full use of the penetration capabilities of two shaped charge, and the penetration effect is greatly improved.
