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 theory of Karman plate refinement, the buckling behavior of a simply supported rectangular plate subjected to bidirectional compression was investigated. The generalized large-deflection Karman equation with transverse shearing effect was applied to the analysis. The analysis results show that the refinement theory of Karman plate considering lateral shear has higher accuracy than other theoretical solutions and finite element numerical solutions.
