You can also search for this author in … 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

WebJan 1, 2024 · Despite the fact that the Rayleigh-Lamb wave propagation in linear viscoelastic solids has been explored (Coquin, 1964, Romeo, 2001, Sharma, 2005, Sharma and Othman, 2007), there is still much room to investigate electroelastic wave propagation with the consideration of material viscosity. WebThe trick is to divide by p or q in convenience. Using the numerical values d = 1, c L = 1.98, c T = 1, we divide equation for the +1 exponent by p and the equation for the -1 exponent by … WebRayleigh-Lamb frequency equations for symmetric and anti-symmetric, asymptotic results for short and long wavelengths, complete discussion of frequency-wave number diagrams for complex k, significance of imaginary branches for edge boundaries, the Lame modes. 7.
