Title: The effects of displacement discontinuity derivatives on wave propagation—II
Abstract: Displacement discontinuities and inertial forces in an elastic solid can be represented as body forces. Fully dynamic, 3-dimensional treatments of largely arbitrary body force fields in half-spaces with, respectively, traction free and zero-displacement surfaces are given. The effects of the body force at the observation point, its value over the half-space surface, and its divergence and curl in the half-space on each component wave in the displacement signal are studied. The relations of the solution to the unbounded solid problem and the Helmholtz potentials for the body force field are also noted. The results indicate the general effects of body force derivatives on the wave propagation, and will be a guide for future work on displacement discontinuity and inertial force response.
