Numerical Analysis of Segmented PELE Penetrating Multi-layer Target

To achieve efficient damage, we simulated the penetration of segmented penetrator with enhanced lateral effect (PELE) on the 4-layer metal target and analyzed the influence of projectile velocity and layer thickness on the terminal effect.The results showed that the segmented PELE projectile performed better penetration than the normal PELE projectile and the diameter of crater produced by segmented PELE projectile was larger than that produced by its rod counterpart.When the projectile passed through the targets, the peak radial velocity of PELE shell increases with the increasing target layer thickness while the length of broken shell did not change with it.The peak radial velocity and length of broken shell was found to increase with increasing segmented PELE projectile velocity after penetrating the first layer and reach a maximum when the projectile velocity was 1.4 km/s after penetrating the second and third layer.After penetrating the fourth layer, the peak radial velocity and the length of broken shell increased with increasing projectile velocity.
