塑性力学流动理论的相似非耦联变分原理

引入了流动理论的相似非耦联方程的概念，建立了流动理论的相似非耦联差动原理，基于该差动原理，建立了塑性力学流动理论的相似非耦联势能原理和余能原理及修正相似非耦联能和余能原理，这些变分原理是在相似非耦联的模型体和原型体之间实现学场量转换的理论依据，也是金属成形过程和光塑性力学模拟研究的理论基础。

Similarly Non-Coupled Variational Principles for Flow Theory of Plasticity

The conception of the similary no-coupled equations is first introduced in this paper. the similary no-coupled potential energy principle and the complementary energy principle for the deformation theory in plasticity are established by applying weighted residual method to the similary no-coupled eqngtions. In use Lagranges multiplier method on the potential energy and the complementary energy principles. generallied the similary no-coupled potential energy principle and complementary energy principle are set up.These variational principles have laid theoretical foundations for the transformations of displacement, strain and stress fields between plastic and elastoplastic similary no-coupled models and prototypes.
