Journal ArticleDOI
Time-Frequency Analysis of the Dispersion of Lamb Modes
TL;DR: The ability to characterize Lamb mode dispersion through a time-frequency analysis (the pseudo-Wigner-Ville distribution) was demonstrated and theoretical dispersion curves were calculated and are shown to be in good agreement with experimental results.
Journal ArticleDOI
Lamb Wave Assessment of Fatigue and Thermal Damage in Composites
TL;DR: In this article, the Lamb wave velocity is compared to modulus measurements obtained using strain gage measurements in the first experiment and the velocity is monitored along with the crack density in the second.
Journal ArticleDOI
Finite Element and Plate Theory Modeling of Acoustic Emission Waveforms
TL;DR: In this paper, a comparison between two approaches to predict acoustic emission waveforms in thin plates was made using properties for both isotropic (aluminum) and anisotropic (unidirectional graphite/epoxy composite) materials.
Journal ArticleDOI
The propagation characteristics of the plate modes of acoustic emission waves in thin aluminum plates and thin graphite/epoxy composite plates and tubes
TL;DR: In this paper, a high fidelity transducer was used to determine the direction of motion of a source in the case of aluminum and graphite/epoxy composite materials using the Reissner-Mindlin theory combined with lamination theory.
Journal Article
Advanced AE Techniques in Composite Materials Research
TL;DR: In this paper, the effects of modal wave propagation over larger distances and through structural complexities are characterized and understood. And the authors apply Modal AE concepts to the interpretation of AE on larger composite specimens or structures.
