Predicted by Rayleigh in 1885, surface waves represent waves localized in the vicinity ofextendedboundaries(surfaces)of?uidsorelasticmedia. Intheidealcase of an isotropic elastic half-space while the Rayleigh waves propagate along the surface, the wave amplitude (displacement) in the transverse direction exponentially decays with increasing distance away from the surface. As a resulttheenergyofsurfaceperturbationsislocalizedbytheRayleighwaves within a relatively narrow layer beneath the surface. It is this property of the surface waves that leads to the resonance phenomena that accompany the motion of the perturbation sources (like surface loads) with velocities close to the Rayleigh one; (see e. g. , R. V. Goldstein. Rayleigh waves and resonance phenomena in elastic bodies. Journal of Applied Mathematics and Mechanics (PMM), 1965, v. 29, N 3, pp. 608-619). It is essential to note that resonance phenomena are also inherent to the elastic medium in the case where initially the | | 出版日期 | Conference proceedings 2005 | | 关键词 | Wave; algorithms; crystal; diffraction; modeling; non-destructive testing; stability | | 版次 | 1 | | doi | https://doi.org/10.1007/1-4020-2387-1 | | isbn_softcover | 978-1-4020-2386-6 | | isbn_ebook | 978-1-4020-2387-3Series ISSN 1568-2609 | | issn_series | 1568-2609 | | copyright | Springer Science+Business Media B.V. 2005 |
