Abstract

The surface stress effects on the Rayleigh wave propargation characteristics in elastic solids with a distribution of laser induced atomic point defects are studied. The frequency equations for waves are obtained and analized. It is found that the Rayleigh waves are generally dispersive; and in the case of low frequency with residual surface tension, a critical wave length exists, below which the propagation of Rayleigh waves is not possible. This critical wave length depends on both the residual stress and the defect distribution.
