活性 PELE 侵彻钢筋混凝土毁伤效应仿真研究

The impact/deflagration-induced damage effect of reactive penetrator with enhanced lateral effect (PELE) on reinforced concrete target is studied by using the finite element analysis software to simulate the behaviors of PELE acting on a reinforced concrete target. A numerical simulation model for describing the impact response process of the reactive materials core is established based on the ignition growth model. The validity of the numerical simulation model is verified according to the test results of a ballistic gun. The calculated results of the simulation model are in good agreement with the test results. On this basis, the damage characteristics of active PELEs against the reinforced concrete targets under the conditions of different impact velocities and shell thicknesses are studied. The results show that the through-hole size of reinforced concrete target increases at first and then decreases with the increase in impact velocity and shell thickness, while for the collapse size, the impact velocity of projectile is the main influencing factor.
