发展性破坏
增量失稳

Numerical method of shakedown analysis based on kinematical - type theorem for incremental collapse and its applications
增量破坏型机动安定性分析方法及其应用
In this thesis , two shakedown rules respectively for alternating plasticity and incremental collapse is given as the theoretical basis of upper - bound shakedown analyses , numerical procedures for solving for the upper shakedown loads respectively for alternating plasticity and incremental collapse are provided
提出了极限载荷与安定载荷包络图的概念，并将其应用到地基的安定性分析中，使得计算的结果更加清晰、明了。
Because the kinematically - admissble cyclic strain rate field required in kninematical - type theorem of shakedown analysis is rather difficult to be constructed , shakedown analysis based on kinematcal theorem cannot be directly applied . some conditions of kinematical - type shakedown theorem are released by ksnig and then the shakedown rules respectively for alternating plasticity and incremental collapse are obtained , for the numerical method based on the upper - bound theorem is formulated
两种方法的特点是：运用一种分级循环加载方式来寻找机动许可的塑性应变率场，利用这两种机动安定准则的特点来判断结构的安定性，从而得到机动安定性分析的安定载荷。
