摘要
利用基本解和域外奇点技术导出了弹性力学平面问题的非奇异虚边界积分方程,然后利用虚边界元-边界子段法对导出的积分方程进行数值求解.研究结果表明,本文方法在精度和数值稳定性方面均优于边界配点法.
The non_singular fictitious boundary integral equations are derived by using the fundamental solutions and the singular points exterior to domain techniques. Then the equations are solved by the fictitious boundary element_boundary segment method. The given numerical examples show that the accuracy and numerical stability of the proposed method are superior to those of boundary point method.
