A thorough review was made of existing experimental data applicable to the impact of high velocity projectiles with semi-infinite metal targets. Empirical equations relating depth of penetration and crater volume to properties of the projectile and target were derived based upon the assumptions that 1 projectile shape does not affect crater shape for projectiles which range from spheres to cylinders up to one caliber in length, and 2 craters are hemispherical. Both of these assumptions are supported by the available data. Additional data andor a rigorous theoretical treatment of the problem are required to evaluate the utility of the equations at higher impact velocities.
