摘要
本文用边界单元法分析了弹性结构的简谐运动问题以及弹性波的绕射问题.对含有动力基本解的奇异积分建议一种较简便的计算方法;用弹性波绕射问题的边界元解法计算了无限介质内孔附近的动应力集中.若干数值实例说明了方法的正确性与有效性.
The harmonic motion of elastic structures and the diffraction of elastic waves have been analyzed in the paper by the Boundary Element Method . A simple calculation method is suggested in the paper for the singular integral containing the fundamental solution to the dynamic problem and the dynamic stress concentration around a hole in the infinite region is calculated by the BEM. for the diffraction of elastic waves. Examples show that the method is reliable and efficient.
