Ultrasonic Guided Waves in Solid Media
TL;DR: The semi-analytical finite element method (SAFE) has been used for guided wave modeling as discussed by the authors, which has been shown to be useful in the analysis and display of non-destructive testing.

Modeling wave propagation in damped waveguides of arbitrary cross-section
TL;DR: In this article, a semi-analytical finite element (SAFE) method for modeling wave propagation in waveguides of arbitrary cross-section is proposed, and the dispersive solutions are obtained in terms of phase velocity, group velocity, energy velocity, attenuation and cross-sectional mode shapes.

A review on non-destructive evaluation of rails: State-of-the-art and future development:
TL;DR: In this article, the authors systematically inspected for internal and surface defects using various non-destructive evaluation (NDE) techniques during the manufacturing process of a rail and found that the defects were mostly caused by internal defects.

Floquet–Bloch decomposition for the computation of dispersion of two-dimensional periodic, damped mechanical systems ☆
TL;DR: In this paper, wave heading and frequency are used to scan the k-space and estimate the dispersion properties of undamped waveguides with various levels of damping, resulting from active control schemes or the use of shunted piezoelectric patches.
Journal ArticleDOI
Guided wave inspection potential of defects in rail
TL;DR: In this article, the results of experiments they have conducted on rail at test tracks and on an operating railroad are provided. But the results are limited to the use of noncontact air-coupled and electromagnetic acoustic transducers as receivers of sound energy emanating from rail.

Ultrasonic Waves in Solid Media
TL;DR: In this article, the theory of elasticity was introduced and basic formulas and concepts in complex variables in the theory and application of wave propagation were discussed. But the authors did not consider the effects of wave scattering on the wave propagation experiments.
