Surface Particle Motion of Rayleigh Waves in Prestressed Heterogeneous Orthotropic Elastic Half Space

Inder Singh Gupta, Amit Kumar

The motion of the surface particles of Rayleigh waves in the prestressed heterogeneous elastic half space is discussed in detail. The analytical expressions for displacement components are derived and showed that these components are effected by initial stress and inhomogeneity factor. It is also proved that  motion of the surface particles becomes retrograde elliptical in unstressed heterogeneous half space. For λ=0, the ratio of the major and minor axes are derived and showed that the ratio becomes unity at the cut-off frequency.
