应变路径改变时，除了包申格效应和永久软化外，还存在加工硬化停滞和交叉效应。这些复杂的变形行为被认为对板料成形过程和随后的回弹有很大的影响。为了组成，更精确地模拟这些塑性行为，广泛的模型已经成功地开发。特别是，各向同性-随动强化组合模型是强大的，以捕捉在正向和反向加载过程中的金属板材的塑性行为。然而，各向异性屈服和各向异性硬化与随动硬化之间存在着很强的耦合。最近，Barlat等人。（2011）[61]提出了一种基于齐次屈服函数的各向异性硬化模型来描述Bauschinger效应，该模型未使用运动硬化规则进行表述。在目前的工作中，原来的各向异性硬化模型进行了扩展，以捕捉经常观察到的交叉效应，在多级加载和反向加载过程中的加工硬化停滞。扩展模型虽然只新引入了四个系数，但能较好地反映加工硬化停滞和交叉效应的主要趋势。该扩展模型的能力证明与应用程序的两种材料，即高强度钢和低碳钢DC 06。
Except for the Bauschinger effect and permanent softening, work hardening stagnation and cross-effect are often observed deformation behaviors for sheet metals subjected to strain path changes. These complex deformation behaviors are assumed to have great effect on the sheet forming process and the following spring back. To constitutively, and more precisely model these plastic behaviors, extensive models have been successfully developed. Particularly, the combined isotropic-kinematic hardening model is powerful to capture the plastic behavior of sheet metals during forward and reverse loading. However, there is strong coupling between anisotropic yielding and anisotropic hardening with the kinematic hardening. Recently, Barlat et al. (2011) [61] proposed a homogenous yield function based anisotropic hardening model to describe the Bauschinger effect, which is not formulated with the kinematic hardening rule. In the present work, the original anisotropic hardening model is extended to capture the often observed cross-effect during multi-stage loading and work hardening stagnation during reverse loading. Although only four coefficients are newly introduced in the extended model, it can capture well the main trends of work hardening stagnation and cross-effect. The capability of this extended model is demonstrated with applications to two materials, namely, high strength steel and mild steel DC06.
