AN INVESTIGATION OF THE DEBRIS CLOUD PRODUCED BY THE IMPACT OF SPHERES ON THIN METAL SHEETS

Abstract

An experimental investigation of the debris cloud produced by the impact of 1/8 inch. diameter spheres of copper and cadmium on 1/16 inch. sheets of like materials was conducted. Calculations of the energy delivered to copper witness plates by solid and liquid phases of the debris cloud were made using volume-energy relationships. Velocity of the cloud front was determined through use of sequential flash X-rays. Phases of the cloud were determined by employing a combination of photographic, radiographic, and crater measurement techniques. Variations in the phases of the cloud with three selected velocities for each bumper-projectile combination were compared with the predicted phase in the velocity range of 23000 to 3000 ft/sec. Energy, energy density, momentum, and mass delivered to witness plates are determined as a function of cone angle.
