A Crater Expansion Model for High-Velocity Penetration

Abstract

This report explores the possibility of applying the recently developed model for line explosion to the problem of crater formation and growth during the course of eroding penetration. A one-to-one correspondence is shown between each of the five input parameters of the line-explosion model to inputs known during an eroding-penetration event. With such a correspondence, a model to predict the time-dependent crater growth during a penetration event amounts to a direct application of the line-explosion model, using a suitably transformed set of input parameters, derived from the local conditions of the penetration event.
