运动学硬化规则制定的硬化/动态恢复格式进行检查模拟棘轮行为。这些规则的特点是将运动硬化变量分解为组件，其假设是每个组件都有一个临界状态，以便完全激活其动态恢复。讨论其基本特征，作者表明，他们可以预测更少的积累的单轴和多轴棘轮应变比阿姆斯特朗和弗雷德里克规则。还与多层和多表面模型进行了比较，发现本规则中的简单模型与用非弹性（或塑性）应变率代替总应变率的多层模型相似。这项工作的第二部分涉及应用实验。
Kinematic hardening rules formulated in a hardening/dynamic recovery format are examined for simulating ratchetting behavior. These rules, characterized by decomposition of the kinematic hardening variable into Components, are based on the assumption that each component has a critical state for its dynamic recovery to be activated fully. Discussing their basic features, the authors show that they can predict much less accumulation of uniaxial and multiaxial ratchetting strains than the Armstrong and Frederick rule. Comparisons with multilayer and multisurface models are made also, resulting in a finding that the simple one in the present rules is similar to the multilayer model with total strain rate replaced by inelastic (or plastic) strain rate. Part II of this work deals with applications to experiments.
