PERFORATION OF ALUMINUM PLATES WITH OGIVE-NOSE STEEL RODS AT NORMAL AND OBLIQUE IMPACTS

Perforation experiments were conducted with 26.3 mm thick, 6061-T651 a luminum plates and 12.9 mm diameter, 88.9 mm long, 4340 R(c) = 44 ogiv e-nose steel rods. For normal and oblique impacts with striking veloci ties between 280 and 860 m/s, we measured residual velocities and disp layed the perforation process with X-ray photographs. These photograph s clearly showed the time-resolved projectile kinematics and permanent deformations. In addition, we developed perforation equations that ac curately predict the ballistic limit and residual velocities. Copyrigh t (C) 1996 Elsevier Science Ltd.
