THE TENSOR GREEN FUNCTION OF ELASTICALLY ANISOTROPIC HEXAGONAL MEDIUM

In this report, components of the tensor Green function of elastically anisotropic hexagonal medium are derived by the Lifshitz and Rosentsveig method. The result is given in a general form suitable for any hcp metal. The result is exact and, in contrast to previous studies, contains no the type of uncertainty 0/0 in the transition to the isotropic limit. As an example of its use, we consider displacements and stress fields generated by a infinitesimal prismatic dislocation loop lying in the basal plane of Zr.
