A PROPOSED SCALING LAW FOR HYPERVELOCITY IMPACTS BETWEEN A PROJECTILE AND A TARGET OF DISSIMILAR MATERIAL,

Abstract

The initial particle velocity produced in a target struck by a hypervelocity projectile is taken to be a significant parameter in determining target penetration. It is found that one can fit a large body of experimental data by assuming that penetrations are linearly proportional to this velocity for projectiles of a given mass and velocity striking a given target. The relation is found to hold over the projectile-density range of 1.75 to 19.3 gm/cc. Using other hypervelocity scaling laws, the relation is extended to apply to projectiles of any dimension. Based on this relation, the scaling factors were calculated for nine metals and volcanic tuff over a wide velocity range, and the results are presented graphically.
