自动考虑剪切变形的轴对称壳单元及对层合壳计算的应用

摘要:

推导了一种中厚壳和薄壳都运用的轴对称壳单元。它假设了独立结点转角，计入了剪切变形，而在薄壳情况下自动符合薄壳理论。以它为基础构造了能自动考虑剪切效应的层合壳单元。

Abstract:

An axisymmetric shell element for both mid-thick and thin shells are presented.Independent nodal rotaions are assumed and transverse deformation is included.The element is automatically suited to thin-shell theory in the thin shell case. Based on it,an el
