摘要
基于各种各样的变分原理建立有限元模型是工程上普遍采用的方法。本文论述了弹性力学三类变量广义变分原理及其修正形式，并给出了最一般意义的三类变量广义变分原理等价性的一种证明方法。
Establishing finite element models on the basis of various variational principles is a general method applied in engineering.In this paper,the generalized variational principles involving 3 variables in elasticity and their modified form were discussed.The proving method was given that the most generalized variational principles involving 3 variables are identical.
