The response of an elastic medium to torsional line loads applied on the surface of a cylindrical cavity, and having a harmonic time-dependence, 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 applications and along the bore surface, are presented. The dynamic effect is represented by dynamic amplification factors and it is shown that, compared to the static case, the resulting outward radiating waves increase the effective radial penetration of the response.
