摘要
本文以文［１］为基础，提出了一种修正的二维曲壳等参元，并用之分析了承受轴对称荷载的层会复合材料旋转天的几何非线性问题。数值算例表明：该单元精度较高，对多层复合材料厚薄壳均是有效的。
In this paper, a modified two-dimensional isoparametric element for curved thick shell is proposed based on reference [1]. Using the element, geometric nonlinear analysis of laminated composite shells of revolution subjected to axisymmetric load is conducted. Numerical examples show that the element is efficient and valid for both thin and thick shells.
