Empirical Analysis of Projectile Penetration in Rock

Abstract

The data base consists of normal impact and penetration data for rock (11 tests) and for concrete (12 tests, used as a baseline). The test projectiles had ogive noses, diameters between 76 and 203 mm, masses between 5.9 and 613 kg, and impact velocities from 251 to 809 m/s. The rock penetration equation is given in dimensional form and also in nomogram form. Calculated results are compared with badly scattered bomb penetration data for granite and sandstone. The equation gives about the same result as a least-squares linear fit to the data.
