| 摘 要： | 本文提出一个分析复合材料板壳的样条有限点法，建立了静力分析、热效应分析、稳定性分析及动力分析的新计算格式。这个方法是以B样条函数、高阶剪切变形理论及变分原理为基础而建立的，由于采用样条离散化，不存在剖分协调问题。利用这个方法分析复合材料板壳，不仅计算简便，而且精度也高。

| Abstract: | In this paper, the spline finite point method for analysis of laminated compsite plates and shells is presented. The computational schemes of static problems, thermal effects, stability problems and dynamic problems are established. This method is based on cubic B-spline functions, a higher-order shear deformation theory and a varitional principle. The dissected compatible problems are avoided because spline partition is used. It is shown that the method is effective and accurate for analysis of laminated composite plates and shells. |
