基于将局部变形乘性分解为弹性变形和塑性变形，提出了弹塑性材料的一般本构方程。两种替代方法进行了讨论：一种是弹性变形被用作一个独立的变量，和其他的应力是一个独立的变量。适当的材料对称性的定义，它表明，塑性自旋是各向同性材料的理论缺席。作为一个例子，给出了一个简单的扩展的分析。
Based on a multiplicative decomposition of local deformation into elastic and plastic deformations general constitutive equations of elastic-plastic materials are proposed. Two alternative approaches are discussed: one in which the elastic deformation is used as an independent variable, and the other in which the stress is one of the independent variables. The appropriate material symmetries are defined, and it is shown that the plastic spin is absent in the theory of isotropic materials. Analysis of a simple extension is given as an example.
