The boundary integral equation (BIE) method proposed by the authors in an earlier paper addressed scattering from internal penny-shaped and elliptical cracks in the frequency domain and was solved for normal incidence of an L-wave at intermediate and short wavelengths. In this paper the BIE code was used to solve for scattering by cracks of the same kind insonified by dual Twave fields incident under 45° angles. This solution was used to construct an approximate solution to the problem of scattering from a surface-breaking crack perpendicular to the free surface and insonified by a single T-wave field incident under a 45° angle.
