| 摘 要： | 本文在渐近有限元模型的基础上，进一步完善了渐近分析过程，修正了有关物理量的量级，给出了形式简洁且物理意义清晰的剪切修正项。改善后的模型能较好地反映横向剪切效应对复合材料层板屈曲特性的影响。本文用算例验证了改善后模型的合理性，并得出了一系列有实用价值的结论。

| Abstract: | In this paper,a consummated asymptotic expansion procedure is presented on the basis of the asymptotic finite element model reported by Xie Yu and Xie Zhicheng.By reevaluating the order of magnitude of the variables,a modified shearing term with concise formation and clear meaning is derived.Thus the effect of transversal shearing deformation on the buckling characteristics of composite laminated plates can be investigated more accurately by means of the modified model.The reasonability of the present model is demonstrated by numerical examples and a series of conclusions with practical value are approached. |
