ON THE INITIAL CONDITIONS OF THE HYPERVELOCITY IMPACT OF A SPHERICAL PROJECTILE ON A SEMI-INFINITE TARGET.

Abstract

Based on physical and geometrical considerations, the initial conditions for the problem of a spherical projectile impacting normally on a semi-infinite target are derived. 'Initial conditions', as used here, are implicitly defined as the geometry and 'state' of the projectile and target materials during a time in which uniform compression exists. Results amenable to experimentation are discussed and an example that illustrates a test for the theory is presented. (Author)
