Application of Time Dependent Green’s Function Method to Scattering of Elastic Waves in Anisotropic Solids

The propagation and scattering of elastic waves provides a valuable tool for the QNDE of composite materials. Since, in general, the composite materials are highly anisotropic, it is important to develop theoretical methods for calculation of wave propagation characteristics in anisotropic media. A lot of work has been done on transient wave propagation in isotropic media but not much in anisotropic media (see, for example [1,2] and other references given there)
