Predicting the ultimate bending capacity of concrete beams from the “relaxation ratio” analysis of AE signals
TLDR
In this paper, the authors present an alternative approach to the problem, based on "testing" the real structure rather than trying to model it, and they describe experiments on reinforced concrete (RC) beams, representative of bridge beams.About:

Advanced structural health monitoring of concrete structures with the aid of acoustic emission
TL;DR: In this article, a comprehensive review of the acoustic emission (AE) technique for its applications in concrete structure health monitoring is presented, with highlights on the limitation of the individual parameter-based approaches when adopted on site.
Acoustic Emission 방법의 공학적 응용
TL;DR: The TÜV Rheinland has many years of experience and practice in NDT techniques and strives to provide clients with the most fitted and tailored nondestructive method for their pressure equipment while offering reliable, time and cost-efficient solutions as mentioned in this paper.

Dimitrios G. Aggelis,D. V. Soulioti,N. Sapouridis,Nektaria-Marianthi Barkoula,Alkiviadis S. Paipetis,Theodore E. Matikas +5 more
TL;DR: In this article, different acoustic emission indices are correlated with the accumulation of damage and the type of source, and the amplitude distribution of acquired signals is very sensitive to micro-cracking, while individual mechanisms like matrix cracking and fibre pull-out can be distinguished by the average frequency of the corresponding signals which exhibits a severe decrease at the moment of main.
Journal ArticleDOI
Fracture process zone size and true fracture energy of concrete using acoustic emission
TL;DR: In this paper, the size-independent fracture energy is computed using the expressions given in the boundary effect model by least squares method since over-determined system of equations are obtained when data from several specimens are used.
Journal ArticleDOI
Non-Destructive Evaluation for Corrosion Monitoring in Concrete: A Review and Capability of Acoustic Emission Technique
TL;DR: The capability of the AE technique to detect corrosion occurring in real-time makes it a strong candidate for serving as an efficient NDT method, giving it an advantage over other NDT methods.

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.

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.

Damage assessment of reinforced concrete beams qualified by acoustic emission
TL;DR: In this article, a criterion based on the Kaiser effect of acoustic emission (AE) is proposed in the recommended practice recently published by the Japanese Society for Non-Destructive Inspection to assess the damage levels of the structures.
