Description

This paper is concerned with exact solutions and approximate solutions in the high-frequency domain for scattering of time-harmonic waves by surface-breaking cracks and cracks which are located near a free surface. Both incident surface waves and incident body waves have been considered. The high-frequency approximate solutions are generally based on elastodynamic ray theory. Some approximate solutions based on the Kirchhoff approximation have been included for comparison.
