In order to further improve the explosively formed projectile (EFP) penetration depth and penetration aftereffect, the liner applies threelayer eccentric sub hemisphere structure The penetrator forming process of shaped charge warhead with threelayer eccentric sub hemisphere structure was simulated by using ANSYS/LS-DYNA software The influence factors on the molding such as curvature radius, wall thickness, material and so on are analyzed. The results show that the threelayer liner structure can be used to form the EFP tandem warhead with the forward and after parts separated. When the liner material is copper, the radius of curvature and the charge diameter ratio is 0.9, the total liner wall thickness is 6mm, wall thickness ratio for three-layer liner is 1:3:2 the penetrator forming effect is good.
Key words： three-layer liner; shaped charge penetrator; EFP; numerical simulation
