Abstract

An experimental and analytical study was performed on the mechanics of oblique perforation of projectiles in metallic plates. The purpose was to determine the dependence of the velocity drop on the angle of impact for prescribed mechanical and physical properties of the projectile and the target plate. The ballistic experiments were carried out with 0.22 inch caliber lead bullets on target plates of commercially pure aluminum and an aluminum alloy which ranged from 2.0 to 60 m in thicknees. Transient measurements were taken which included high speed photograph' 4i:h(: perforation process. The theoretical model that had been developed previously by the authors for the case of normal perforation woo modified to include the effects of the angle of impact. The experimental observations for the present teat conditions indicate that the only essential modification to the analysis to the use of the total projectile path ast the effective target plate thickness. The comparison of the results shows reasonably good agreement between experiments and theory. 'Lecturer, Department of Materials Engineering Technion Israel Institute of Technology presently, N.R.C.
