摘要：

阐述了金属薄板在塑性变形中的应变硬化行为，总结了基于增量塑性理论的弹塑性材料本构模型推导方法，重点分析了经典随动硬化模型中的Prager-Ziegler硬化模型、Mroz硬化模型、Armstrong-Frederick硬化模型、Chaboche 硬化模型、Geng-Wagoner硬化模型、Yoshida-Umemori硬化模型和Teodosiu-Hu硬化模型的理论基础及其应用范围，为今后的相关研究提供参考。

The strain hardening behavior of thin metal sheet during plastic deformation was elaborated. The method of determining the elastic-plastic constitutive model based on the incremental plastic theory was summarized. Emphasize was put on the theoretical origin and application field of the classic kinematic hardening models, such as Prager-Ziegler's model, Mroz's model, Armstrong-Frederick's model, Chaboche's model, Geng-Wagoner's model, Yoshida-Umemori's model and Teodosiu-Hu's model，which provide references for the further studies.
