Penetration performance of axisymmetric U-shape-nose grooved projectile into aluminum target: Theoretical model and experiment

Abstract The penetration performance of projectiles is closely related to their nose shape as it influences the kinetic energy penetration of a rigid projectile. One new type of projectile, which is entitled U-shape-nose grooved projectile, is introduced in this study. A theoretical model, which describes the structural characterization of U-shape-nose grooved projectile, is constructed here to investigate the penetration characters into an aluminum target. Moreover, comparative penetration experiments were conducted to investigate the penetration performance of U-shape-nose grooved projectil...
