Abstract

The dynamic mechanical properties of concrete and reinforced concrete targets subjected to high-speed projectile impact loading have a significant influence on the impact resistance of protective structures. In this study, high-speed projectile penetration and perforation of concrete and reinforced concrete structures was carried out to determine the high-energy impact loading. The failure behaviors of projectile penetration and perforation of the concrete and reinforced concrete targets were investigated, and the destruction characteristics of the targets were measured. An analytical model was established using the principle of minimum potential energy. The results show that the theoretical predictions are consistent with the experimental data, indicating that the energy method is effective for predicting the dynamic mechanical properties of concrete and reinforced concrete targets under high-speed projectile penetration.
