Abstract
The effects of a hypervelocity projectile striking complex targets have been investigated. The targets consisted of metallic and low-density shock attenuating layers and void regions. The major features of the targets were systematically varied to correlate changes in the targets with the projectile's effectiveness in damaging the targets. Two-dimensional numerical simulations were done with the Eulerian computational fluid dynamics program PINON. Projectile effectiveness against the various targets was measured by determining the maximum pressure, pressure integral, P 2τ value, and hole size at several locations in the targets.
