SH波散射与界面圆孔附近的动应力集中

SCATTERING AND DYNAMIC STRESS CONCENTRATION OF SH-WAVE BY INTERFACE CIRCULAR HOLE 1)

  • 摘要: 建立了求解含有界面圆孔的二种不同弹性组合介质中SH波的散射和界面圆孔附近的动应力集中问题的Green函数法给出了一个具有半圆形缺口的弹性半空间水平表面上任意一点承受时间谐和的出平面线源荷载作用时位移函数的基本解取基本解作为Green函数,建立起问题的定解积分方程最后给出了界面圆孔的动应力集中的算例和结果,并讨论了不同介质参数的组合对动应力集中的影响

     

    Abstract: The present paper investigates the problem of SH-wave scattering and dynamic stress concentration by bi-material structure possessing cylindrical interface hole Green’s Function method is used here, which means a special essential solution suitable to the present problem must be constructed In terms of wave functions expansion method and Graf formula, we give the construction course for the special Green's function, and deduce it strictly from the essential solution for a perfect half space impacted by ...
