摘要
本文研究一类粘着型界面裂纹的弹性波散射问题．文中利用积分变换和积分方程方法推导了确定这类问题的奇异积分方程组．采用围道积分技术和切比雪夫多项式展开技术，得到了待定系数的非线性代数方程组．最后本文给出裂纹尖端粘着区的大小和界面应力的数值结果．
In this paper, scattering of elastic waves by an interface crack with linear adhesive tips in a layered half space is considered . By use of integral transform and integral methods, the singular integral equations of this problem are derived, which are transformed into a set of algebraic equations by means of contour integration and Chebyshev polynomials extending techniques. The numerical results on adhesive region and stress amplitudes are given in this paper.
