Rayleigh lamb
WebLamb waves have emerged as a valuable tool to examine long plate-like structures in a faster way compared to conventional bulk wave techniques, which make them attractive in non-destructive testing. However, they present a multimodal and dispersive nature, which hinders signal identification. Oblique incidence is one of the most known methods to … 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.

WebA plane strain, time-harmonic, symmetric Rayleigh-Lamb wave propagates in the plate and is normally incident upon the end x =0. The problem of determining the resulting reflected wave field is solved by the “method of projection”, a method developed by the authors for solving corresponding problems in elastostatics.
