拟协调大变形矩形扁壳元及其应用

A Large Deflection Quasi-Conforming Rectangular Shallow Shell Element and Applications

本文采用拟协调元方法,引用简化的扁壳应变分量,构造了一个大变形矩彤扁壳单元,该单元适用于薄板壳的线性和几何非线性分析,数值例题的结果表明本文单元的性态很好。

In this paper, a large deflection rectangular shallow shell element is created based on quasi-conforming technique, which is applicable to linear and geometrically nonlinear analyses of thin plates and: thin shells.The behaviour of the element is shown good by the numerical examples in the paper.
