AN EXPERIMENTAL STUDY OF HIGH VELOCITY IMPACT AT NORMAL AND OBLIQUE INCIDENCE ON MULTIPLE SPACED 2024-T3 ALUMINUM PLATES, GENERAL MODEL
Abstract
An experimental investigation was made of projectile impact on multiple, spaced 2024-T3 aluminum plates at incident projectile velocities on the order of 13,000 ft./sec. The leading plate was either 1/4 in. or 1/16 in. in thickness, with succeeding plates of 1/8 in. in thickness. The spacing between plates was 1-3/4 in. (measured normal to the front plate from the back of the front plate to the front of the following plate). Projectile impace occurred at normal (0 degrees) and oblique (60 degrees) incidence. The projectiles were solid copper and annealed steel spheres of 3/16 in. nominal diameter. The results obtained showed that no more than two plates were completely penetrated. For normal impact, it was found that the hole diameter could be predicted from existing empirical relations.
