摘要
采用Reissner-Mindlin板理论考虑横向剪切变形影响,并计及板的初始几何缺陷,用文[1]提供的二次摄动法给出完善和非完善,各向同性和正交各问异性中厚板在面内双向压缩作用下的屈曲载荷关系曲线和后屈曲平衡路径。
Based on Reissner-Mindlin plate theory, the buckling and postbuckling analysis of isotropic and orthotropic moderately thick rectangular plates under biaxial compression is presented. The initial geometrical imperfection of plate is taken into account. The analysis uses a perturbatiion technique to determine the interactive buckling loads and postbuckling equilibrium paths. Numerical results are presented that relate to the performance of perfect and imperfect, isotropic and orthotropic moderately thick rectangular plates.
