Analysis of the bending Problem of Sandwich Plate by Least Square Method

摘要: 本文根据夹层板的分解刚度法原理,以正弦级数与多项式作为试函数,采用加权残数中最小二乘法分析了矩形夹层板的弯曲问题。分析结果表明,此法简便,精度高。

Abstract: In this paper, according to the principle of the method of splis rigidities of Sandwich plate, sine series and polynomial are takenas trail fancton, using the least square method of the Method of Weighted Residuals, We analyze the bending problem of the rectangle sadw ich plate. The results show the preserl method is convenienle and high accuracy.
