Magneto acoustical emission in nanocrystalline Mn–Zn ferrites
TL;DR: In this article, the magneto-acoustic emission (MAE) activity along hysteresis loop was found to be proportional to the losses during the same loop, regardless of the composition, grain size and temperature.

Deep Learning-Based Acoustic Emission Scheme for Nondestructive Localization of Cracks in Train Rails under a Load
TL;DR: In this article, the authors proposed a nondestructive single-sensor acoustic emission (AE) scheme for the detection and localization of cracks in steel rail under loads using a deep learning algorithmic model.
Journal ArticleDOI
Acoustic emission in plastic deformation of metals (review). Report 1
A. A. Yudin,V. I. Ivanov +1 more
TL;DR: In this article, a review focusing on attempts to establish quantitative relationships for construction of a theory of acoustic emission in plastic deformation is presented. Butler et al. discuss the role of deformation at the crack tip and the influence of the grain size of a polycrystalline material.
Journal ArticleDOI
Acoustic emission during plastic and superplastic deformation of a Zn-0.4% Al alloy
TL;DR: In the case of superplastic materials, AE is extremely weak at the outset of deformation, and is virtually absent during super-plastic flow as mentioned in this paper, and a significant increase in AE occurs with increasing grain size or strain rate, when the alloy is nonsuperplastic.

Daily and annual electromagnetic noise variation and acoustic emission revealed on the Gran Sasso mountain
TL;DR: In this article, a very simple experimental procedure was used to discriminate rare acoustic emission (AE) events due to elastic waves from false AE (FAE) signals, due to electromagnetic noise, and the reliability of this separation was confirmed by the reported amplitude and time distributions of AE events, typical of fracture dynamics and those of FAE events, similar to those of noise.

Acoustic emission - 2: Acoustic emission amplitudes
TL;DR: In this paper, the amplitude of acoustic emission is discussed and its usefulness as a source of information is discussed. And the amplitude sorting method has a significant future role as part of a more complete characterization of emission signals.

Mechanism of brittle fracture of rock: Part I—theory of the fracture process
TL;DR: In this article, the authors presented results of investigations aimed at establishing a mechanism of brittle fracture of rock in compression and tension, and provided experimental verification of the postulated mechanism of rock fracture.
