摘    要:金属材料循环塑性本构方程和循环粘塑性本构方程是固体力学中近10多年来一个十分重要的领域。本文评述了金属材料非比例循环塑性界限面本构理论、内时理论和循环粘塑性本构理论及其某些进展,对某些模型中非比例度定义,材料在复杂应变幅值历史、非比例循环加载历史以及其它历史下的强化规则和流动规则进行了分析与评价,在此基础上对循环本构理论的发展趋势提出自己的看法。

关 键 词:循环塑性  循环粘塑性  非比例加载  界限面理论  内时理论

Abstract:The constitutive equations of cyclic plasticity and cyclic viscoplasti- city of metallic matcrials have been a very important field of solid mechanics for morc than ten years,In the paper, bounding surface constitutive theories,the endochronic lheory and viscoplastic theories of metallic materials under non- proportional cyclic loadingsnre prcsented together with recent advances,The definitions of nonproportionality, the mcmory effects on complex strain am- plitude history,and material hardcning and flow rules under nonproportional cvclic loading histories and other historics are analysed and reviewed.Based on those,some comments are madcon the development trends of cyclic constitutive theories.
Keywords:cyclic plasticity  cyclic viscoplasticity  nonproportional loading  bounding surface theory  endochronic theory
