摘要
变载作用下弹塑性结构的安定性研究是一个有实际意义的课题，而结构的安定性与材料的强化规律有很大关系。本文对几种典型的强化模型下的结构安定性进行了研究，给出了在随动强化和组合强化条件下结构实现安定的条件，所得结论简化了应变强化条件下结构的安定分析。
It is important in engineering applications to study the shakedown of structures under loads changing with time. The shakedown of structures is related to the strain-hardening models of materials used. The present paper considers the shakedown problems of structures under several strain-hardening models. The shakedown conditions of kinematic-hardening and mixed -hardening structures are given. The conclusions obtained here simplify the shakedown analysis of strain-hardening structures.
