摘要

Green's tensors are determined for a point force in layered horizontally homogeneous solid media at fixed horizontal wavenumber κ due to a Fourier-Bessel series expansion. The media may consist of an arbitrary mixture of solid layers, bounded by homogeneous half-spaces at both ends. A finite element technique is proposed for solving a resulting two-point ordinary differential equation (ODE) boundary value problem for the wavefield using either a variational form or a propagator matrix approach. A brief discussion of the boundary element method for elastic-wave scattering from a bounded object using new Green's tensors is outlined.
