Abstract
The steady state problem of the scattering of an incident Rayleigh wave by an elastic three-quarter space (270° wedge) is considered. The problem is reduced to the numerical solution of a pair of Fredholm integral equations of the second kind. The kernels of these equations consist of elementary functions. The reflection and transmission coefficients can be computed from two independent equations, which provides a check on both the accuracy and correctness of the results. The method used can be extended to other wedge angles.
