Study on the implementation of reinforced concrete target in PELE with hood

Abstract

In order to analyze the influence of the material and shape of the hood of the medium-caliber PELE warhead on the damage effect of the reinforced concrete wall with PELE projectile, the three-dimensional nonlinear dynamic finite element program LS-DYNA was used to numerically simulate the penetration of the PELE projectile with the hood of different shapes and materials into the 0.25 thick thin reinforced concrete wall target at various velocities. The results show that under the same conditions, the hollow cone shaped phenolic resin hood can achieve better damage effect of reinforced concrete wall.
