“…Most of the papers have used AE to identify the destruction process of materials in structures [21,22,23,24,25,26,27,28] including crack orientation [29,30,31]. The AE method is still used and improved for the purpose of the identification of failure processes [32,33,34].…”

The paper presents the identification of the destruction process in a quasi-brittle composite based on acoustic emission and the sound spectrum. The tests were conducted on a quasi-brittle composite. The sample was made from ordinary concrete with dispersed polypropylene fibers. The possibility of identifying the destruction process based on the acoustic emission and sound spectrum was confirmed and the ability to identify the destruction process was demonstrated. It was noted that in order to recognize the failure mechanisms accurately, it is necessary to first identify them separately. Three- and two-dimensional spectra were used to identify the destruction process. The three-dimensional spectrum provides additional information, enabling a better recognition of changes in the structure of the samples on the basis of the analysis of sound intensity, amplitudes, and frequencies. The paper shows the possibility of constructing quasi-brittle composites to limit the risk of catastrophic destruction processes and the possibility of identifying those processes with the use of acoustic emission at different stages of destruction.

“…In the field of civil engineering, the AE technique has been widely used for structural health monitoring (SHM) and assessment of steel corrosion damage, especially in the evaluation of corroded concrete structures [6,7,[18][19][20][21][22]. This AE technique was operated without disturbances to the processes and progressions associated with concrete structures [23][24][25][26].…”

The acoustic emission (AE) technique is known as a non-destructive testing (NDT) method, which is effective for assessing corrosion in concrete structures. This study aims to utilize the AE technique, for the assessment of pre-corroded concrete specimens, which are under load testing. Experiments were carried out on small-scale pre-corroded specimens, which were subjected to monotonic loading. The results showed that the majority of the beam specimens failed with shear cracks. Three AE parameters, namely acoustic emission hits, as well as the RA and AF values, were also used, in order to assess the flexure behaviour of the pre-corroded beam specimens. These experiments helped to understand the flexural behaviour of pre-corroded specimens, which were under a loading test, via the use of the AE technique.

“…Previous research work focused on the correlation between AE and the failure processes of each of the composite components based on the sound spectrum [ 40 , 41 , 42 , 43 , 44 , 45 ]. It has been found that, for the accurate recognition of composite failure processes, the AE recording should be expanded to include the analysis of each sound separately (as well as a single signal in a very small range of frequencies) and the analysis of the range of sounds corresponding to a given mechanical effect with the use of an acoustic spectrum.…”

Identifying the Range of Micro-Events Preceding the Critical Point in the Destruction Process in Traditional and Quasi-Brittle Cement Composites with the Use of a Sound Spectrum

et al. 2021

This paper presents the possibilities of determining the range of stresses preceding the critical destruction process in cement composites with the use of micro-events identified by means of a sound spectrum. The presented test results refer to the earlier papers in which micro-events (destruction processes) were identified but without determining the stress level of their occurrence. This paper indicates a correlation of 2/3 of the stress level corresponding to the elastic range with the occurrence of micro-events in traditional and quasi-brittle composites. Tests were carried out on beams (with and without reinforcement) subjected to four-point bending. In summary, it is suggested that the conclusions can be extended to other test cases (e.g., compression strength), which should be confirmed by the appropriate tests. The paper also indicates a need for further research to identify micro-events. The correct recognition of micro-events is important for the safety and durability of traditional and quasi-brittle cement composites.
