变厚度扁球壳的非线性分析

THE NONLINEAR ANALYSIS OF THE SHALLOW SPHERICAL SHELLS WITH VARIABLE THICKNESS

摘要: 本文利用边界元方法分析了变厚度扁球壳的非线性问题。引入了与变厚因素有关的等效载荷q,利用板的初等函数基本解,而不是直接寻求变厚扁球壳的基本解,使原问题的难度大大减少,采用了连续性强、精度高的样条函数插值,即使在划分节点取得较少的情况下,结果的精度是令人满意的。

Abstract: In this paper,we analyse the shallow spherical shells with variable thickness by the boundary element method.After introducing the equivalent load q with respect to (N,W, H).We reduce the problem to the analysis of a thin plate.The results with satisfactory pricision can be obtained even when fewer degree of freedom are implemented. Keywords:Shallow spherical shell with variable thickness,BEM,nonlinear analysis.
