【 摘 要 】

The present study analytically investigates the propagation of edge waves in a pre-stressed homogeneous visco-elastic plate. The plate is initially stressed in horizontal direction only. The solution for potential function and displacement components of the edge wave propagation have been obtained separately. Dispersion equation of edge wave has been established in closed form.The horizontal tensile and compressive initial stress parameters give the remarkable effect on the phase velocity of edge wave propagation.
