摘要
本文从Karman板大挠度方程出发,以挠度为摄动参数,采用直接摄动法,研究了简支矩形板在面内双向压缩作用下的后屈曲性态.本文同时考虑了板初始几何缺陷的影响.计算结果与实验结果的比较表明二者是一致的.
In this paper, a perturbation method is employed to deal with von Karman equations of large deflection plates by taking deflection as perturbation parameter. The postbuckling behaviors of simply supported rectangular plates under biaxial compression are investigated in detail. The initial imperfection effects on the postbuckling are also studied. It is found that the theoretical results are in good agreement with experiments.
