| Abstract: | 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. |
