Numerical analysis of oblique impact on reinforced concrete

This study proposes a simple but efficient methodology based on the equivalent inclusion method and finite element analysis. Oblique impacting is considered to investigate the residual velocity and ricochet limit of an ogive-nose steel projectile with various impact velocities against a reinforced concrete slab. The computational results are compatible with Tate's formula for the ricochet limit as a function of the impact velocity. The proposed methodology is useful for designing defense structures, and the ricochet limit is one of the important parameters that govern the performance of a weapon system. The methodology can be further developing for designing the protection of military structures and nuclear power plants against high velocity projectiles.
