Explosively shaped charge
WebShaped charges do generally melt, and the latent heat of fusion and density are both critical to the depth of penetration for the molten jet. Copper is an easy choice that meets both of these criteria. For example, lead has high density but only a little more than a third of the latent heat of fusion of copper. WebThe whole process of formation, flying and penetration of explosively-formed projectile (EFP) is simulated by a 3D coupled hydrocode of Ls_dyna. The caliber of the shaped charge is 60 mm and EFP is a kind of overturned shaped charge. The Arbitrary Lagrangian–Eulerian (ALE) method is adopted to consider the fluid–solid coupling problem.
