摘要： 在考虑外载和温度的缓慢变化，以及屈服应力的温度效应下，借助于运动安定定理，导出了一个既简单又适用的增量破坏准则，并以实例说明了它的应用。

关键词: 结构, 破坏, 塑性变形

Abstract: A simple and applicable incremental collapse criterion is presented by means of the kinematical shakedown theorem under the consideration that external loading and temperature change slowly and dependence of yield stress on temperature. The application of the presented criterion is illustrated by an example.

Key words: Collapse, Plastic deformation, Structure
