The Rayleigh wave dispersion equation for propagation on a curved surface is derived as a parabolic equation, and its penetration depth is analyzed using the curved surface boundary. Reciprocity is introduced to model the diffracted Rayleigh wave beams. Simulations of Rayleigh waves on some canonical ...
Although the solutions in eqn (6) are for 2-D disturbances propagating on a planar interface, similar Rayleigh waves can be propagated on the curved surfaces of 3-D geometries, allowing their use in the inspection of surface areas of a component that might not be directly accessible. Rayleigh...

There are some differences when Rayleigh waves propagate along the edge of a thin semi-infinite orthotropic medium made of laminate or metal crystallic structure. These differences are studied in the paper. 会议名称: Twelfth International Congress on Sound and Vibration (ICSV12): 11-14 July 2005...

We can formalize the above argument by considering a generalization of the approach of Taylor2to include rotation. Miles41noted the importance of including the effects of the parabolic free-surface of a rotating body of liquid when calculating the properties of free-surface waves in rotating systems...
Peculiarities of surface waves, mainly the Rayleigh waves, propagation along curved surfaces play an important role in seismology because of the Earth surface curvature [9.3-6]. In acoustoelectronics the wave propagation on curved surfaces allows us to construct the delay lines for large times [9.7...
