| Abstract: |
| The linear governing equation for the Rayleigh-type waves are formulated and solved with the appropriate boundary conditions at the free surface of an orthotropic half-space with voids. The frequency equation for Rayleigh waves is presented in its non-dimensional form. It is found that these waves are dispersive and also dependent on the void parameters. For different orthotropic materials, graphs are presented to elaborate the effects of various void parameters and wave number on the wave speed. |
