摘要: 应用有限变形的最小加速度原理,推导出了小变形或有限变形构件受到刚性飞射物撞击时的刚塑性运动方程,指出该方法具有直接、简捷和可靠的特点.

Abstract: in this paper, a rigid plastic dynamic equations of the stucture subjected to impact by a rigid projectile are obtained based on the minimum principle in dynamics of elastic-plastic continua with finite deformation. It is shown that the method is reliable and straightforward.
