具有非线性应力应变关系的弹性体的广义变分原理

Generalized Variational Principles in Elasticity with Ncnlinear Stress-Strain Relation

讨论了具有非线性应力应变关系的弹性体的广义变分原理,并用拉格朗日乘子法导出了具有三类独立变量的广义变分原理。

This paper dicusses generalized variational principles for the elastic body withnonlincar strcss-strain relation. The generalized variational principles with three kinds of variational functions for the elastic body with nonlinear stress-strain relation are derived from the method of Lagrange multiplier.
