Numerical Study on Characteristics of EFP with Two Kinds of Liner Materials


Article Preview

The formation, flight and penetration process of explosively formed projectile (EFP) was computed by using nonlinear dynamic finite elements code AUTODYN-2D. 10# steel and Copper are chosen for EFP material calculation and Quasi-spherical EFP was technically designed for small-bore warhead, the configuration of EFP with these two kinds of material was optimized respectively. The decay equation of projectile velocity was used to analyze the velocity variation of Quasi-spherical EFP, the impact velocity was obtained. Characterization of EFP penetrate into A3 steel plate was analyzed by compare the results of 10# steel and Copper, EFP made of these two kinds of material are capable to perforate A3 steel plate with a thickness of 0.45 times diameter of charge.
