Abstract: In this paper, scattering of elastic waves by an interface crack with adherent contact at its tips is considered. By use of integral transform and integral equation methods, the singular integral equations of this problem are derived, which are transformed into a set of algebraic equations by means of contour integral and Chebyshev polynomials extending techniques. The numerical results on contacting region and stresses amplitudes are given in this paper, which show that the dynamic features of this model are complicated, and this model is physically reasonable.
