| 摘 要： | 本文利用翘曲修正理论,通过最小势能原理导出了复合材料叠层板的静力方程。数值计算则采用二维升阶谱有限元技术,用本文方法计算正交铺层矩形叠层板所得的位移、应力分布结果与精确解相比,具有很好的收敛性。

| Abstract: | The sectional warping corrective theory is used. The statics equilibrium equation for composite laminated plates is derived by means of the principle of minimum potential energy. In the plate plane,two-dimension hierarchical displacement functions are adopted during numerical analysis. The obtained numerical results for both displacement and stress distrihution in the thickness direction of a rectanguler bidirectional composite laminated plate are compared tenth the exact solution;as a consequence,the present method is shown to have good convergence. |
