Application of Sub region Function Method for Solving Beam-Board Structure

摘要: 本文根据文献[1]提出的加枚残数法中的分区函数的概念,将其应用于求解带有边梁的薄板问题.并将同一问题采用了有限单元方法^[3]进行了计算.比较两者结果表明,在加权残九法中应用分区函数法是有较强的实用性和有效性.

Abstract: In this paper, the solution to the structure consisting of a bead and a board is given as a result of the application of the subregion function method which was suggested in ref. [1]. The same problem is also computed with finite element method. The comparison between the two results shows that the application of the subregion function in the method of weighted residuals is practical and effective, especially for solving compound structures.
