摘要
本文建立了适用于任意边界条件和几何形状的两参数弹性地基板的边界积分方程,利用微分算子分解的方法导出了三种形式的基本解。文中详细地讨论了两参数弹性地基板的边界元分析过程,分析了一些算例并与已知的解析解和数值解作了比较。数值结果表明,本文方法具有较高的计算精度和计算效率。
In this paper, the boundary integral equations of thin plates resting on thetwo-parameter elastic foundation, which can be applied to arbitrary boundaryconditions and arbitrary geometric shapes are presented. Three kinds of fund-amental solution of plates are derived by means of differential operator analy-sis. The procedure of boundary element analysis for these plates are discussedin detail. Some of numerical examples are given. The results show that accura-cy and efficiency of the method presented are higher than the others.
