Acoustic emission monitoring of reinforced concrete beams subjected to four-point-bending
TL;DR: In this paper, the authors applied acoustic emission (AE) technique and study the damage mechanism of reinforced concrete (RC) beams under four-point bending laboratory experiments are performed on three types of RC beams of grade M30 with 42, 64 and 93% of longitudinal steel against balanced section The damage in the beams are classified into four zones symbolizing formation of micro cracks, visible cracks, steel yielding and concrete crushing.

Crack classification in concrete based on acoustic emission
Kentaro Ohno,Masayasu Ohtsu +1 more
TL;DR: In this article, two crack classification methods are compared and discussed from results of three types of concrete failure tests, and it is shown that the ratios of the shear crack which are identified by Green's functions for moment tensor analysis are good agreement with those by parameter analysis in the case that the proportion of the RA value and the average frequency is set to 1-200.

Classification of cracking mode in concrete by acoustic emission parameters
TL;DR: In this paper, a number of acoustic emission indices are proposed to classify the cracks according to their mode, which can provide a warning against the final failure of a concrete structure during bending.
