Further results for antiplane scattering by a thin strip.
A result, which does not appear to be available elsewhere, concerning the far-field scattering of antiplane waves by a single thin crack in an elastic solid is obtained in this letter. Specifically, the angular shape function is derived, with scattering coefficients expressed in terms of the crack-opening displacement. With this function, numerical values for effective speed and attenuation through a distribution of parallel cracks are obtained.
