Forming and Penetration of Explosive Formed Projectiles-Numerical and Experimental Analyses

xplosive Formed Projectiles (EFP) are applied extensively in anti-armour missiles. However, ue to its complexity in analysis, numerical simulation is widely used. In particular, analysis of FP forming and penetration can be effectively utilized in anti-armour warhead design. In this aper, the forming and penetration of two types of liner, including spherical with variable hickness and polynomial curve, have been simulated by LS-DYNA Code. For comparison and valuation, several ballistic tests have also been carried out as experimental work. The results of umerical simulation, such as penetration depth and crater diameter, have been compared with he experimental results and good agreement have been obtained.
