弹性基础上矩形板热后屈曲分析

THERMAL POSTBUCKLING ANALYSIS OF RECTANGULAR PLATES ON ELASTIC FOUNDATIONS

  • 摘要: 本文给出双参数弹性基础上矩形板在均匀和非均匀(抛物型)热分布作用下后屈曲分析。采用摄动-Galerkin混合法给出完善和非完善矩形板热屈曲载荷和热后屈曲平衡路径。本文同时给出数值算例并讨论各种参数变化的影响。

     

    Abstract: A thermal postbuckling analysis is presented for a rectangular plate subjected to uniform and nonuniform (parabolic)temperature loading. The plate is assumed to rest on a two parameter elastic foundation. The initial geometrical imperfection of plate is taken into account.A mixed Galerkin-perturbation technique is adopted to determine thermal buckling loads and postbuckling equilibrium paths. Numerical examples are presented in which the effects of various parameters are discussed.
