摘　　要：本文对离散的理想塑性结构在给定的外载和初始条件下,讨论了几个动力安定问题。尤其是对其安定时间,本文作了深入细致地研究,并给出了两个有关的重要推论。This paper deals with several dynamic shakedown problems of the discrete elastic-perfectly plastic structures withthe given initial conditions which is subjected to the given external loads.The authors make a thorough and carefulstudy about the adaptation time of the structures,and present two main relevant corollaries.

关 键 词：弹塑性结构 动力安定 安定时间
