Symmetric low-frequency feature-guided ultrasonic waves in thin plates with transverse bends.
TL;DR: This paper focuses on the faster bend-guided mode that is similar to the S0 (fundamental symmetric) Lamb mode in flat plates that is shown to be more strongly generated in smaller angle bends.
Journal ArticleDOI
Guided Wave Propagation in a Plate Edge and Application to NDI of Rail Base
TL;DR: In this paper, the analysis of the trajectories of the two material points, due to waves propagation, shows that the wave packets can be identified as Rayleigh waves and the presence of S0 Lamb mode, with low frequency and low amplitude, has been revealed too.

Local defect resonance of a through-thickness crack.
Igor Solodov,Marc Kreutzbruck +1 more
TL;DR: In this paper, the authors considered the mechanism of development and the attributes of LDR for through-thickness cracks in plates and validated that the LDR is caused by the resonance of the edge waves propagating along the crack faces.

Higher-order finite-element analysis of topographic guides supporting elastic surface waves
TL;DR: In this article, a method of computing the eigenmodes of acoustic waveguides of arbitrary cross section is described, based on a variational formulation of the guided-wave problem.
Journal ArticleDOI
Ridge guides for acoustic surface waves
TL;DR: In this article, a low-velocity flexural mode has been excited on acoustic-surface-wave topographic guides, with structures offering some hope of realisation at high frequencies, very strong confinement of the guided wave is obtained.
Journal ArticleDOI
Some remarks on propagation characteristics of ridge guides for acoustic surface waves at low frequencies
TL;DR: In this article, the plane-stress equations of the theory of elasticity are solved to predict the propagation characteristics of flexural and pseudo-Rayleigh modes of infinitely tall ridge guides for frequencies lower than the lowest thickness-shear frequency of thin plates.

Finite Element Analysis of Piezoelectric Elastic Waveguides
TL;DR: In this paper, a finite element method for the analysis of the mode spectrum of an anisotropic piezoelectric elastic wave-guide with arbitrary cross-section is described.
