摘要
在板的一阶 Karman 型精化理论的基础上,给出了适用于反对称铺层剪切矩形板的广义 Karman大挠度方程,并采用一种位移型摄动技术,求解了四边简支单向和双向压缩作用下的板的后屈曲平衡路径,讨论了板的横向剪切变形、宽厚比和材料特性对板的后屈曲性态的影响。
The generalized Karman equations governing large deflection of laminated angle ply shear deformable rectangular plates are presented based on the first order Karman type refined plate theory. According to the nonlinear Karman equations, postbuckling of laminated angle ply shear deformable rectangular plates with four edges simply supported are studied by using a deflection type perturbation technique. Effects of transverse shear deformation, width thickness ratio and material properties on the postbuckling behavior are discussed in detail. \;
