| 摘 要： | 采用广义傅立叶级数法建立了具有弹性约束的复合材料矩形层板在面内载荷作用下的非线性稳定性控制方程组，并简化为矩阵形式。运用广义傅里叶级数法对控制方程组进行求解，得到相应的载荷一中心挠度曲线。计算结果表明：非对称层合板在面内载荷作用下，一般产生的是横向变形，但在一定的铺层顺序、边界条件、受载方式等情况下，也可能发生分叉型屈曲。

| Abstract: | The nonlinear governing equations of rectangular composite laminated plates with edges elastically supported against rotation were established by generalized Fourier series method.The governing equations were simplified in matrix form.The governing equations were solved by using generalized Fourier double series method and the corresponding load-deflection curves were obtained.The results of calculation showed that unsymmetric laminates under loads in plane produced transverse deflection generally,but in so... |
