In this paper, it has been proved that the well-known Hu-Washizu variational principle is a pseudo-generalized variational principle (pseudo-GVP). The stationary conditions of its functional may satisfy all its field equations and boundary conditions if all the variables in the functional are ...

摘要: 阐述了Hu-Washizu变分原理实际上是一个赝广义变分原理,即虽然其驻值条件满足所有 的场方程及边界条件,但它存在某种约束,为了清楚说明问题,本文构造一些新的赝广义变分原理,用逆拉氏乘子法可以清楚地看出其约束关系,并进一步证明了 Hu-Washizu变分原理和Hellinger-Reissner变分原理之等价定理.关键词:...
variationalprincipleThe paper has proved that Hellinger-Reissner and Hu-Washizu variational principles are but equivalent principles in elasticity by following three ways: 1) Lagrange multiplier method. The paper points out that only a new independent variable can be introduced when one constraint ...

A recent mixed formulation of the Virtual Element Method in 2D elastostatics, based on the Hu-Washizu variational principle, is here extended to 2D elastodynamics. The independent modeling of the strain field, allowed by the mixed formulation, is exploited to derive first order quadrilateral Virtual...
