Abstract : The steady-state response of a semi-infinite solid, with an overlying semi-infinite fluid, subjected at the plane interface to a moving point load is determined for subsonic and intersonic load velocities. The displacements of the solid and the velocity potential of the fluid are obtained in terms of algebraic expressions and single finite integrals which can be readily evaluated numerically. Some numerical results for the displacements at the interface are presented and compared to the results obtained in the absence of the fluid. (Author)
