WebThe antecedent work on Lamb waves is not hard to identify. It was Lord Rayleigh in 1889 who first explained wave propagation along a guided surface [1], and the waves are known as Rayleigh waves today. Following Rayleigh’s work, Horace Lamb, a British applied mathematician, reported the waves discovered in plates in one of his historic publications, … Lamb's theoretical formulations have found substantial practical application, especially in the field of nondestructive testing. The term Rayleigh–Lamb waves embraces the Rayleigh wave, a type of wave that propagates along a single surface. Both Rayleigh and Lamb waves are constrained by the elastic … See more Lamb waves propagate in solid plates or spheres. They are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the direction perpendicular to the plate. In 1917, the … See more Lamb waves exhibit velocity dispersion; that is, their velocity of propagation c depends on the frequency (or wavelength), as well as on the elastic constants and density of the … See more As the frequency is raised, the higher-order wave modes make their appearance in addition to the zero-order modes. Each higher-order mode is “born” at a resonant frequency of the … See more While Lamb's analysis assumed a straight wavefront, it has been shown that the same characteristic equations apply to cylindrical plate waves (i.e. waves propagating … See more In general, elastic waves in solid materials are guided by the boundaries of the media in which they propagate. An approach to guided wave propagation, widely used in physical acoustics, is to seek sinusoidal solutions to the wave equation for linear elastic waves subject … See more The symmetrical and antisymmetric zero-order modes deserve special attention. These modes have "nascent frequencies" of zero. Thus they are the only modes that exist over the entire frequency spectrum from zero to indefinitely high frequencies. In the low frequency … See more This phrase is quite often encountered in non-destructive testing. "Guided Lamb Waves" can be defined as Lamb-like waves that are guided by … See more
