Abstract

Abstract: Research the extreme on specific mass tungsten alloy fragment penetrated and perforated low-carbon steel. For armor-piercing of tungsten alloy spherical fragment against semi-infinite and finite thickness steel on higher projectiles penetration speed, firstly, ultimate penetration depth of the spherical fragment on the diameter in common use was obtained by numerical simulation, at the same time, the relation between ultimate pierced thickness and diameter of the spherical fragment was obtained; Base on these, armor-piercing experiments on different diameter fragments against Q235 steel plate was done, the outcomes on experiments and numerical simulation had better consistency, based on the experiment phenomena and numerical simulation, damage format on the spherical fragment was analyzed under different impact speed. The research results were important value for application.
