Keywords:PELE, numerical simulation, enhanced lateral effect, projectile core material, thickness. 1. Introduction With the increase of the diversity of targets and the mobility of protection, the traditional penetration warhead cannot meet the needs of modern battlefield gradually, and the penetrator with enhanced later effect (PELE) is born.
Numerical simulation of normal and oblique ballistic Feb 01, 2004 · The various numerical simulations presented the details of penetration processes, distributions of energy, stresses etc. of normal and oblique impact at a velocity of 315 m/s. In particular, it was found that the distributions of global kinetic, internal and total energy versus time are similar for normal and oblique impact.
