| 摘 要： | 本文关于薄板的分析采用样条函数插值及结构中的残余应力场用温度参数模拟，解决了薄板结构在交变载荷作用下的安定问题。由于温度参数的引用，使得研究的问题的自由度大幅度减少，文中还对薄板的Ｍｉｓｅｓ型屈服函数进行了线性化处理，它是安定定理的求解线性化的基础，算例表明本文所提出的方法及程序的可行和有效。

| Abstract: | In this paper, spline function is used to interpolate plate structures,and the self-equilibratedresidual generalized stress fields are simulated by the temperature stresses containing temperature pa-rameters,thus,the shakedown analysis of plate structures is transformed to solve a mathematical pro-gram. The degrees of freedom of the problem studied are much decreased for the use of temperatureparameters. The paper also discussed the process of the yield criterion linearization of plate structures,and this is the basis of lincarization of shakedown theorem. The program coded and computing exam-ples show the correctness and effectiveness of the proposed method. |
