GREENS TENSOR FUNCTION FOR LAMBS PROBLEM - THE GENERAL ANISOTROPIC CASE

The complete solution of Lamb's three-dimensional problem of determini ng the elastic disturbance resulting from a point force in a half-spac e is addressed. The derived expression for the half-space Green's func tion is valid for a general anisotropic medium and is given in a two-d imensional space-time spectral representation, which is well-suited fo r numerical evaluation. It is expressed with respect to the displaceme nt and traction vectors involved as well as the full-space Green's dya dic (or displacement tensor) and triadic (or stress tensor) functions.
