| 摘 要： | 材料在经过一定的塑性预应变后，将产生各向同性强化、随动强化及组合强化。本文介绍了在这三种应变强化形式下加载条件（后继屈服条件）的确定方法，并以不锈钢（１Ｃｒ１８ Ｎｉ ９Ｔｉ）为例，给出了幂硬化材料对应各向同性强化和组合强化两种情况下加载条件的数学表达式。

| Abstract: | A material with plastic prestrain shows the property of strain hardening such as isotropic hardening, kinematic hardening or mixed hardening. This paper presents a method to determine the loading condition (subsequent yield condition) of the three strain-hardening rules. Mathematical expressions of the loading condition for isotropic hardening and mixed hardening of power hardening material, such as stainless steel (1 Cr 18Ni 9 Ti), are also given. |
