摘要
基于Ｋａｒｍａｎ型板的精化理论，研究了双向压缩四边简支矩形板的屈曲性态，分析中应用了计及横向剪切效应的广义大挠度Ｋａｒｍａｎ方程。分析结果表明计及横向剪切的Ｋａｒｍａｎ型板的精化理论与其它理论解和有限元数值解相比，具有较高的精度。
Based on the Karman type refined plate theory,the buckling behavior of unsymmetrically laminated angle ply shear deformable rectangular plates with four edges simply supported is analyzed.The latest version of the generalized Karman equations counting for the transverse shear deformation are applied here.The results computed from the present solution have a higher accuracy than other theoretical and numerical results.
