We develop a semi-analytical procedure for calculating the diffraction coefficients for cracks perpendicular to the symmetry axis of a transversely-isotropic medium. The problem is of interest in the mathematical modeling of NDE (non-destructive evaluation) of austenitic steels, which are found in claddings and other welds in the nuclear reactors and can be modelled as transversely isotropic.
