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。
Based on the first-order Karman-type refinement theory of the plate, the generalized Karman’s large deflection equation for the antisymmetrical lay-flat plate is given and a displacement perturbation technique is used to solve the four-sided simple support slip The effects of transverse shear deformation, aspect ratio and material properties on the post-buckling behavior of the plate are discussed.
