ELASTIC WAVES FROM A POINT FORCE IN TRANSVERSELY ISOTROPIC MEDIA

Elastic waves from a point force in transversely isotropic,homogeneous media can be solved through the reflectivity-transmittivity matrix approach.Assuming the point force locates in an imaginary isotropic layer and utilizing potential discontinuities equivalent to a point force in isotropic media,it is quite easy to obtain the displacement field in media.Then let the thickness of the isotropic layer tend to be zero,the solution of the original problem,i.e.,the Green function in tranversely isotropic media is obtained..The final result is independent of parameters of the imaginary layer,which proves this approach is effective to resolve elastic field stimulated by point forces in transversely isotropic media.
