Journal ArticleDOI
Modeling the Propagation of Lamb Waves using a Genetic Algorithm and S-transformation
Xiaoyu Wang,Ibrahim N. Tansel +1 more
TL;DR: In this paper, two time domain models, time delayattenuation (DA) and time delay-attenuation-phase (DAP), are utilized to represent the propagation of Lamb waves in a compact and meaningful model.
Journal ArticleDOI
Excitation of Love Waves in a Thin Film Layer by a Line Source
Hang-Sheng Tuan,S.R. Ponamgi +1 more
TL;DR: In this article, the excitation of a Love surface wave guided by a thin film layer deposited on a semi-infinite substrate is studied and an analytical expression for the bulk wave amplitude as a function of the direction of propagation, the acoustic powers transported by the surface and bulk waves, and the efficiency of surface wave excitation are obtained.
Journal ArticleDOI
Optimized piezoelectric sensor for a specific application: Detection of Lamb waves
Mohamed Rguiti,Sébastien Grondel,Faysal El Youbi,Christian Courtois,Marc Lippert,Anne Leriche +5 more
TL;DR: In this paper, the development and optimization of a new piezoelectric sensor using Lamb waves destined to aerospace structures health monitoring is devoted to the development, optimization, and performance evaluation of the new sensor.
Journal ArticleDOI
Structural integrity monitoring of steam generator tubing using transient acoustic signal analysis
TL;DR: In this article, the Hilbert-Huang Transform (HHT) is used for nonlinear nonstationary signal processing and a moving window is introduced to generate the local peak information from transient series and a zooming window algorithm is developed to localize the structural flaws.
Journal ArticleDOI
Ultrasonic surface crack characterization on complex geometries using surface waves.
TL;DR: Good agreement is shown by comparison of the calculated out-of-plane displacement with experimental results for both cracked and non-cracked specimens, as well as a systematical error possibly due to the inclined crack profile.
