Abstract
SERIOUS discrepancies and considerable variations have been observed in the numerous empirical, semi-empirical, and theoretical equations which have been proposed to describe craters formed in metal targets as a result of hyper-velocity impact1. These inconsistencies in the mathematical models can be attributed to a paucity of precise engineering data and to a basic disagreement about the mechanism of impact. One group of experimenters has attempted to relate the extent of hyper-velocity damage to the mechanical properties of the impacted target; another group has stressed the hydrodynamic model of cratering.
