N2 - 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.
