Diffraction of SH-waves by a Griffith crack in an infinite transversely orthotropic medium Original Research Article

This paper deals with the diffraction of SH-waves by a finite Griffith crack located on a symmetric surface of an infinite transversely orthotropic medium. The Fourier transform technique [1] has been used to reduce the elastodynamic problem to the solution of a set of integral equations. These integral equations have been solved by using the finite Hilbert transform technique and Cookʹs result [2]. The stress intensity factor has been derived for low frequency vibration.
