This study presents mechanism of the local damage of concrete plate subjected to high velocity impact by rigid projectile. First, characteristics of the local damage of concrete plate subjected to collision by rigid projectile were explained. Then, a numerical model which can describe dynamic behavior of concrete was investigated in terms of combination of failure model and strain rate effect of concrete. Based on the proposed numerical model, mechanism of the local damage of concrete plate was illustrated. Finally, energy transition of initial kinetic energy of projectile and energy consumption in eroded area were discussed
