    Abstract
  • The numerical simulation of projectile shape effects on craters in hypervelocity impact on thick alloy aluminum target at normal angles has been carried out using the AUTODYN hydro-codes in this paper. The results of 2D and 3D simulation are given. The effect of projectile aspect ratios with different shapes and impact orientations etc. on damage characteristics sizes and shapes of craters produced by hypervelocity impact on alloy aluminum targets have been investigated with the same mass and velocity. The simulation results are compared with the crater created by spherical projectiles. It is shown that projectile has a larger aspect ratio, it has a larger crater depth; the damage characteristics sizes and shapes of craters created by non-spherical projectiles impact are different with the projectile shapes and impact orientations.
