Original Abstract
The paper deals with the electromagnetic emission (EME) and the acoustic emission (AE), which arise during the crack generation in mechanically stressed concrete specimens. The objective of the research consisted in verifying the crack generation waveform model for quasi-brittle material damaging processes. It appears that the crack position, as determined from the lag of the acoustic signal behind the electric one, indicates elevated mechanical stress concentration points in the test specimen. Experiment results thus prove to be in a good agreement with the modelling results for the crack spatial distribution in the specimens.
