Abstract
Numerical simulations of different PELE jacket and filling materials are carried out to research the influence of the materials characteristics on PELE effects. The results indicate that the materials characteristics have obvious influence on PELE effects. For jacket materials, the elastic modulus and density are the key factors that influence PELE effects, the maximum radial speed and scattering angle of fragments, and the penetration hole size of 4340 steel are larger than these of tungsten alloy, thus the PELE effects of 4340 steel are better. For filling materials, the elastic modulus is the key factor influencing PELE effects, the maximum radial speed and scattering angle of fragments, and the penetration hole size of PE, nylon and aluminum increase successively, the aluminum filling material has better PELE effects.
