摘要：

A model of oblique penetration of a rigid projectile into a thick elastic-plastic target has been developed (Roisman et al., Int J Impact Engng 1997; 19: 769-95) which incorporates stress-free boundary conditions at the rear surface of the target. The main objective of the present work is to validate the theoretical model by comparison with new experimental results for normal and oblique penetration of a rigid projectile into a thick plate of Al 6061-T651. Good agreement between theory and experiment is exhibited for the projectile residual velocity and the crater shape. (C) 1999 Elsevier Science Ltd. All rights reserved.
