八节点等参数板弯元

Isoparametric plate bending element with eight nodes

本文根据Hu-Washizu广义变分原理建立一个八节点等参数板弯元,采用插值函数并项及应变应力取相同的插值函数的方法来提高运算效率,取得较好的结果。

In this paper, a isoparametric plate bending element with eight nodes is presented on the basis of Hu-washizu principle. With the method of combining the items of interpolation and giving the same interpolation to the stress and strain, we get high efficiency of computation.
