动载荷下弹塑性随动强化结构的安定分析

Shakedown Analysis for an Elasto - plastic and Kinematic Work - hardening Structure Subjected to Dynamic Loading

在考虑动载荷和温度影响情况下,借助于分段线性加载面对弹塑性随动强化结构进行了安定分析,提出了一人动力安定定理。文末又以实例说明了它的应用。

This paper analyses the shakedown of an elasto -plastic and kinematic wo - hardening structure by means of the piecewise linear yield surface. The influence the dynamic loading and temperature is considered. A new theorem of dynamic shak down is presented. A practical example is made to demonstrate the applications of th theorem.
