Elastic Waves in Transversely Isotropic Media
Christoffel’s equation (15.21) splits up into one linear equation and one quadratic one for any direction of the wave normal only in the case of a hexagonal crystal or a transversely isotropic medium; this is the only case in which it has a comparatively simple general solution .
