The effect of initial stress and viscosity on the propagating love waves in a prestressed viscoelastic layer over a rigid half space is considered. It is shown that wave number group velocity and phase velocity are highly affected by initial stresses and viscosity. The Paper presents a study on Love wave’s propagation in a prestressed viscoelastic layer over laying a right half-space. The characteristic frequency equation is obtained and the variation of wave number with frequency under the combined effect of initial stress and viscoelasticity is analysed in detail.
