摘　　要：本文用边界元法分析了纤维增强复合材料正交各向异性层合板的屈曲性态。为了克服在用边界元法求解正交各向异性层合板屈曲时寻求相应的基本解的困维,本文采用了双重傅立叶级数和引用等效荷载的概念,建立了层合板屈曲临界荷载的特征方程。算例说明了本文方法的可行性和有效性。The buckling behaviour of orthotropic fiber-reinforced composite laminates is analyzed by the boundary element method. In order to overcome the difficulties in finding the fundamental solution to the buckling of orthotropic laminates in boundary element method, the double Fourier series are used and a concept of equivalent load is introduced. The eigen equations of the critical loads of the laminated plates are determined. The computed examples show that the method is reliable and efficient.
