THE FIELD OF A POINT-SOURCE IN AN ELASTIC HOMOGENEOUS ANISOTROPIC MEDIUM

A new method is applied to obtain the Green's tensor for a point sourc e in a general anisotropic elastic homogeneous unbounded medium in the form of an integral over the surface of a unit sphere. This represent ation can be used to obtain, in the time domain, simple expressions fo r the displacement held generated by a localized source with an arbitr ary time dependence. The static term of the Green's tensor is transfor med into an easily calculable form. A high-frequency asymptotic expres sion is derived for the Green's tensor.
