Computer Simulation Study of Kinetic Energy Projectiles Penetrating Concrete Targets

Abstract:
Kinetic energy projectiles can cause penetration damage to concrete fortifications. In order to study the effects of kinetic energy bullet velocity and concrete strength on the penetration depth, a computer numerical simulation model is established against the classical kinetic energy bullet penetration experiment, and the calculated datas of empirical equations were compared and studied. The results show that the simulation model can obtain the penetration depth and target deformation results which are more consistent with the experiments; the kinetic energy bullet velocity and concrete strength have a greater influence on the penetration depth, and the calculated datas of different empirical formulas differ greatly; the kinetic energy bullet velocity and the penetration depth of 30MPa strength concrete model are fitted, and a fitting formula with higher accuracy and wider speed range was obtained. This formula can quickly calculate the penetration depth of the kinetic energy bomb and provides a reference for the study of the penetration depth of the kinetic energy bomb.
