Journal ArticleDOI
Dispersion of Lamb waves in a honeycomb composite sandwich panel.
TL;DR: Some of the useful properties of guided Lamb type waves are investigated, using analytical, numerical and experimental methods, in an effort to provide the knowledge base required for the development of viable structural health monitoring systems for composite structures.
Journal ArticleDOI
Rayleigh to Lamb wave conversion at a delamination-like crack
TL;DR: In this paper, a detailed study of the interaction of Rayleigh surface waves with defects in a thick aluminum plate is carried out using numerical simulations and laboratory experiments, which are shown to partially result in Lamb wave conversion.
Journal ArticleDOI
Lamb wave propagation in a plate with step discontinuities
TL;DR: In this article, the free-end Lamb wave reflection at a free end as well as the interaction of Lamb waves with upward and downward step discontinuities is solved using an analytical approach.
Journal ArticleDOI
Structural health monitoring of cylindrical structures using guided ultrasonic waves
TL;DR: This work addresses several aspects of the propagation of guided waves in cylinders, especially the analysis of reflection and transmission at discontinuities using finite element and boundary element methods.
Journal ArticleDOI
Damage detection in multi-wire cables using guided ultrasonic waves
TL;DR: In this paper, a damage detection algorithm based on the Hilbert transform of the recorded signals from induced guided ultrasonic waves is presented, which is fully automated and distinguishes between wave packets from different waves independently.
