By taking into account of both dilatational and deviatoric deformations, the formulae of stress components in semi-infinite viscoelastk media under the action of a constant vertical concentrated force applied at the free surface arc derived. The media treated here-in is supposed to be a Kelvin-Voigt solid, a Maxwell solid or a solid which can be expressed by the four-element model, M-K, respectively. In connection with the formulae of deformations, only the vertical displacements of the free surface are given. Besides, the expressions for lateral stresses, in the media, due to uniformly distributed vertical stresses on the free surface, are also obtained. Finally, a numerical example for illustrating the differences between the several models is worked out.
