Projectile-Flow Effect for Long Rod Penetration.

Abstract

There have been indications that the flow stress level in the plastically flowing part of a long rod penetrator may have a significant influence on the penetration efficiency. We refer to this phenomenon as the projectile-flow effect. We performed a series of AUTODYN runs to investigate the projectile-flow effect. We show that when the projectile material hardens/softens as it flows, its penetration can be reduced/enhanced significantly. We also show that the projectile-flow effect is less pronounced at high velocities, and is enhanced for high L/D penetrators. It seems that the L/D effect at high L/D may be explained by the projectile-flow effect.
