A proposed sealing law for hypervelocity impacts between a projectile and a target of dissimilar material

R. L. Bjork, A. E. Olshaker

ResearchPublished 1965

A technique for scaling the penetration depths occasioned by projectiles of various materials striking targets at hypervelocities. The initial particle velocity produced in targets by such projectiles is taken as a significant parameter in determining target penetration. It is found that one can fit a proportional to this velocity for projectiles of a given mass ans velocity striking a given target. The relation is found to hold over the projectile-density range of 1.75 to 19.3 gm/cm cubed. Using other hypervelocity scaling laws, the relation is extended to apply to projectiles of any dimension. Based on this relation, the scaling gactors have been calculated for nine metals and volcanic tuff over a wide velocity range. The results are presented graphically.
