Abstract: The present paper discusses the influence of different interaction of steel bars and concrete in LS-DYNA code on the perforation of reinforced concrete. Numerical simulations on the experiments by Hanchak S J, et al, are conducted and redisplay the deformation and failure of projectiles and reinforced concretes. Also this paper analyzes the effect of impact location of reinforced concrete on the terminal ballistic performance. The proposed numerical simulation methods may be further employed to discuss the structure, mesh size and area density of reinforcing bars on the perforation of reinforced concrete.
