The scattering of a time-harmonic elastic wave by a half-plane-shaped crack ∑ is modelled by a dirichlet boundary value problem. This is shown to be equivalent to a system of wiener-hopf equations.

Scattering problems (or diffraction problems) consist in studying the field resulting from a wave incident upon an obstacle. This can for example be an acoustic or an electromagnetic wave. In general, these are complicated time-dependent problems, but often a justified hypothesis can be made, which allows time considerations to be dismissed.
