Abstract
Analysis of hole formation on the hypervelocity impact penetration of metal targets subjected to projectiles is presented. The proposed approach establishes one governing equation for target, projectile and fluid (air) using mixture theory assuming incompressibility in the full Eulerian framework. The Eulerian formulation is attractive for the analysis of hole formation on penetration because it can generate new free surface in natural manner. We validate computational results comparing with a physical based hole diameter relationship.
