Propagation of Rayleigh waves over a thermo-viscoelastic half space with a slightly curved free space

363-373

Propagation of Rayleigh waves over a thermo-viscoelastic half space with a slightly curved (cylindrical) free space is considered. It is shown that, like in the case of curved elastic space, the surface displacement components and the temperature for the curved thermo-viscoelastic half space can be expressed in terms of the corresponding quantities in a plane-faced half space with a unit surface line source. Expressions for corrections to the Rayleigh wave displacements due to the curvature are obtained. Some special cases are also derived, and solution of frequency equation is considered. The roots of frequency equations are obtained approximately and numerical results are obtained.
