Stress and displacement correction terms resulting from application of n subsonica1iy moving point load to the free surface of the infinite half-space are obtained using lourier transform techniques (the load moves subsonica1ly with respect to the longitudinal and transverse wave speeds). It is shown, for the supersonica11y travelling point load that the solution is given, in the limit as the load velocity becomes large, by the well known solution of Sauter for the impulsive point load.nAnalytic, function theory is used to predict the existence of Rayleigh waves on the free surface of the infinite half-space and Stoneley waves along the welded interface between two dissimilar solid media. A brief analysis shows that free-running waves are also possible on the interior surface of an infinitely long cylindrical cavity. These waves are dispersive, however, because of the introduction of a characteristic length.
