BALLISTICS EXPERIMENTAL AND NUMERICAL INVESTIGATION ON DAMAGE EFFECT OF REACTIVE PELE PENETRATING REINFORCED CONCRETE

Through the ballistic drive test of the reactive PELE penetrating reinforced concrete, the through hole and caving size of the reinforced concrete target were obtained. Finite element analysis software Ansys/Lsdyna was used to study the impact deflagration damage effect of reactive PELE on reinforced concrete targets. Based on the ignition growth model, a numerical simulation model is established. The calculated results of the model are in good agreement with the experimental results. On this basis, the damage characteristics of reinforced concrete targets affected at different impact velocities and shell thicknesses were studied. The results show that with the increase of impact velocity and shell thickness, the through hole size of concrete target increases first and then decreases, which is mainly determined by the match between projectile penetration time and the reaction time of reactive materials. For the caving size, projectile impact velocity is the main influencing factor.
