均质样条边界元列式方法

The Formulistic Method for Spline Boundary Element in Homogeneous Media

采用样条插值函数将均匀介质的边界积分方程离散为代数方程组.通过对均质样条边界元列式方法的改进,最终使总体系数矩阵成为带宽很窄的条带阵、提高了计算精度和解题效率,为在较普及的微机上实现运算奠定了基础.

The boundary integral equation in homogeneous media was dispersed into algebraic equations through the use of spline function.By the improvement of the formulistic method for spline boundary element,the whole quotient matrix was turned into a strip one which had a very narrow strip width.The calculative precision and efficiency to solve problems were improved.lt lays the foundation of calculation on microcomputers which become more popular.
