摘要 本文提出并证明了随动强化结构不可能发生累积塑性破坏,即交变塑性是指唯一可能的破坏形式,并且与时间无关的平衡力系对结构的安定性没有影响。 It is pointed and proved that it is impossible for a kinematic-hardening structure to involve incremental collapase, and it can only fail by alternating plasticity. Time-inde pendent equilibriant forces have no influence on shakedown of kinematichardening structures.
