Cartridge design of a high-speed projectile considering mass abrasion

Aimed at normal and oblique penetration into semi-infinite concrete/limestone targets by a high-speed projectile, an axis drag force was employed to reflect the continuous variation of the nose shape. With considering the transverse load in the cases of asymmetrical mass abrasion and oblique penetration, a method was proposed to analyze the yield of a normally/obliquly penetrating projectile. The initial impact velocity limit was deduced by taking the projectile stability into account when the cartridge thickness was given, and the influences of different projectile/target conditions were discussed.
