The dynamic response is analyzed. The numerical simulation method has been used to projectile penetrating concrete for many years. However, most previous research study has concentrated on the cuboids concrete model. Very few studies have been conducted to investigate the penetration process of complex concrete model. In this study, numerical simulations of laboratory tests are conducted to show the penetration process of wedge concrete model. A double scalar damage model based on the concept of continuum damage mechanics is applied to modeling the failure of concrete. In the numerical model of wedge concrete, the wedges with different angles are modeled. By the numerical simulation, the relationship of projectile penetrating into the wedges concrete with different angles are demonstrated.
