摘要

摘要: 本文以摄动法给出了矩形板屈曲和后屈曲全过程的弹塑性分析. 本文同时讨论了初始几何缺陷对矩形板后屈曲性态的影响.计算结果表明,矩形板非弹性屈曲对初始缺陷是敏感的.计算结果与实验结果的比较表明二者相当一致.

Abstract: Full-range analysis for the buckling and post buck ling at rectangular plates under in-plane compression has been made by perturbation technique which takes deflection as its perturbation parameter.In this paper the effects of initial geometric imperfection on the postbuc kling behavior of plates have been discussed. It is seen that the effect of initial imperfection on the inelastic postbuckling oj plates is sensitive. By comparison, it is found that the theoretical results of this paper are in good agreement with experiments.
