Effects of the liner materials on penetration capability of explosively formed projectiles

Abstract

Numerical simulations are carried out to study the effects of the liner material (Al, Cu, Mo, W, Ta) on the shape, mass, velocity, kinetic energy, length-to-diameter ratio, penetration depth and hole-diameter of MCT-83 mine (explosively formed projectile). The results of these parameters present the potential capability of each liner material used to fabricate explosively formed projectiles. Cu has get the maximum penetration depth value while Mo has the largest hole-diameter. The research results help to choose the material of liner suitable for each type of EFP warhead and for each different purposes.
