Simulation Studies on the Influence of Impact Velocity on the PELE Penetrated and Broken Reinforced Concrete

Abstract:

In order to study the effect of the impact velocity for the penetrator with enhanced lateral effect (PELE) penetrating reinforced concrete (RC) targets, penetration of PELE filled nylon against RC target using the different velocity is simulated by LS-DYNA finite element method software. Simulation shows that the impact velocity have definite effect on broken RC. On condition of PELE having penetrated target, with farther increase of impact velocity, the area of PELE broken RC on the direction of decrease firstly and augmentation thereafter, the residual velocity after penetrating target is less at the same time; Take into account validity of lateral effect and general launching condition, selecting the impact velocity at the range of 800 m/s-1300 m/s is suitable for PELE broken RC. The simulation results are in good agreement with those of the experiments.
