review text: The response of an elastic medium to a ring-load pressure on the surface of a cylindrical cavity, having a harmonic time dependency is studied. Integral representations of the stress and displacement fields are obtained, and numerical results along a radial line emanating from the point of load application are presented. The response is observed to occur due to P-, S- and surface waves whose radiation depends on a critical forcing frequency. The dynamic effect is represented finally by dynamic amplification factors, and the increased radial penetration of the response is analyzed in terms of the radiation of the excited waves.
