Abstract
The mass loss of the nose of projectile is an obvious phenomenon in high-speed penetration into concrete target. The mass loss percentage depends linearly on the impact velocities of projectile according to experimental data fitting results. A semi-empirical model, which can calculate the ogive-nose shape change due to mass loss, is developed in this paper. The modified penetration model shows that the penetration depth is influenced by nose erosion.
