In this paper we demonstrate that the presence of thermoelectric anisotropy, no matter
how small, can be exploited to unmask the presence of cracks and holes in metals. This is in
direct contrast with situations involving isotropic metals where such detection is not
possible. Although such a phenomenon will occur for all types and shapes of cracks and
holes, for simplicity we shall demonstrate our theoretical and numerical modeling on the
more mathematically tractable case of a cylindrical hole aligned along an axis of symmetry
of an anisotropic metal medium.
