Abstract
Using the finite element software LS-DYNA to establish the shell, fuse, fuse base, cover and charge model of a semi-armor-piercing warhead, and simulating penetration for three different alloy shell of the warhead at a velocity 300m / s, target thickness 34mm . Researching on warhead penetration process, at the same time, analyzing the effects of warhead penetration performance, speed and overload at different alloys material. The results showed that: G50 is the best performance penetrating material, slightly better than the 30CrMnSiNi2A materials. TC4 material is the lowest penetration performance compared to the G50 and 30CrMnSiNi2A material.
