Impact of Concave and Convex Solid Surfaces By Liquid-Like Projectiles

Abstract

A theoretical and experimental investigation of the normal impact of a flat-ended liquid slug onto ductile cylindrical solid targets is presented. The liquid slug is simulated by wax which is known to behave as a liquid in high speed impact situations. Both concave and convex types of the cylindrical target were used. The pattern of damage of the impacted Aluminum targets reveals compressed and ripple-damaged surfaces. While the convex target can be treated well by the modified model put by Kiter & Salem[5], the same cannot be said to the concave target.
