摘要: 本文分析具有正交模量特性的复合材料层合扁曲板在轴压下的屈曲和初始后屈曲问题。作为应用的例子,分析了两种不同铺层形式的长扁曲板的轴压屈曲和初始后屈曲问题,并得出了一些对工程结构设计有参考价值的结论。

Abstract: The buckling and the initial post-buckling behavior of laminated composite shallow panels with orthotropic modular property under axial compression are analyzed. The expressions of critical load and initial post-buckling parameters and the asymptotic solutions of post-buckling state are given by solving the first two perturbation equations. As examples of application, the buckling and initial post-buckling behaviors of long shallow panels of two different laminatings, cross-ply and angle-ply, are consi-dered. Some useful conclusions are drawn.
