有转角自由度的矩形板壳单元

RECTANGLE PLANE SHELL ELEMENT WITH ROTATIONAL DEGREES OF FREEDOM

本文讨论了一个新型的单元———带转角自由度的矩形平板壳体单元 ,推导了该单元的应力矩阵和刚度矩阵。通过与其他方法的比较 ,证明了所建立的单元列式简单 ,计算精度高 ,是一种方便、可靠的工程分析方法。

A new finite element - rectangle plane-shell element with rotational degrees of freedom is given via the derivation of the stress matrix and stiffness matrix of the element. The reliability of the method is verified by comparision with the popular method.
