本文综合介绍了描述各向异性塑性行为的最新模型。第一部分概述了经典模型。此外，讨论的重点是各向异性公式的基础上发展的线性变换理论和张量表示，分别。这些模型适用于不同类型的材料：体心、面心和六角形紧密排列的金属。简要回顾了用于表征和模拟金属板和管在双轴载荷下的各向异性塑性行为的实验方法，以及用于预测和建立极限应变的模型和方法。分析了一些专门用于计算成形极限曲线（FLC）的商业程序的能力。
This paper presents synthetically the most recent models for description of the anisotropic plastic behavior. The first section gives an overview of the classical models. Further, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively. Those models are applied to different types of materials: body centered, faced centered and hexagonal-close packed metals. A brief review of the experimental methods used for characterizing and modeling the anisotropic plastic behavior of metallic sheets and tubes under biaxial loading is presented together with the models and methods developed for predicting and establishing the limit strains. The capabilities of some commercial programs specially designed for the computation of forming limit curves (FLC) are also analyzed.
