Abstract:A solution of Green’s function is presented for a point dynamic load in theinterior of an elastic half-space which fully satisfies the boundary conditions on the freesurface. By means of the modified Hankel functions,the infinite integral is transformed intofinite ones in the complex domain, which makes the evaluation of Green’s function easierand more conveniently This solution serves the theorectical basis for the application ofboundary element method in the analysis of dynamic soil-structure interaction ...
Keywords:Green's function  elastic half-space  dynamic excitation inside the domain
