TL;DR: In this paper, the wavelet transform was applied to acoustic emission (AE) signals from scratch tests on stainless steel samples with Cr or Ti nitride coatings obtained by physical vapor deposition, in order to characterize the coating adherence failure mechanisms.

TL;DR: In this paper, a wavelet transform analysis of hot dip galvanized samples with different corrosion levels was carried out, where wavelet power was distributed in different frequency bands, according to damage mechanisms.

TL;DR: In this article, the authors investigated the applicability of acoustic emissions for assessing the low-cycle fatigue damage in reinforced concrete (RC) exterior beam-column subassemblages, which are especially vulnerable parts of the RC frames when subjected to earthquakes.

TL;DR: In this paper, scratch tests using Acoustic Emission (AE) were performed on corroded hot dip galvanized samples, and different coating damage mechanisms could be assigned to different bands.

TL;DR: In this article, a cyclic test is conducted on an exterior connection until its failure, and a tentative formula is proposed, to predict the level of damage and the closeness to failure of the connection on the basis of the acoustic emissions recorded by one piezoelectric sensor located near the critical zone (i.e., the beam-end and beam-column joint).
