The Effect of Projectile Strength on Crater Formation
Abstract
The influence of projectile strength on cratering was investigated for projectiles of four aluminum alloys impacting semi-infinite aluminum targets over the velocity range of 1 km/sec to 5.0 km/sec. Final crater dimensions and peak shock pressure were selected as parameters for comparing the influence of projectile strength. The experimental results showed that crater diameters were not significantly influenced by varying projectile strength. The crater depths were found to vary appreciably with strength at lower velocities but to become virtually the same at 3.5 km/sec for the series of projectile alloys investigated. Experimental results for peak shock pressures were inconclusive due to the large scatter in the experimental data.
