| 摘 要： | 本文采用退化的等参壳元分析了复合材料板、壳结构的几何非线性特性。数值计算表明：与各向同性材料不同，即使在很小的载荷和挠度下，几何非线性对复合材料结构的影响也是相当显著的。

| Abstract: | Applying degenerate isoparametric element, this paper has studied geometrical nonlinear response of composite plates and shells. Numerical results indicate that unlike isotropic metallic structures , the geometric effects on composites could be very significant even at small loads and deflections. Degenerated isoparametric shell element is an efficient element for the analysis of laminated composite plates and shells undergoing large displacement and rotations. |

| Keywords: | composites plate shell finite element geometrical non-linearity. |
