Vliv způsobu mechanického zatěžování betonových vzorků na signály elektromagnetické a akustické emise

Original language description

The paper deals with the generation of electromagnetic emission (EME) and acoustic emission (AE) response, which results from the load being applied to rectangular concrete specimens in two different ways. In the first case, the specimen is stressed by aplain pressure exerted by the pressing machine jaws on it. In the second case, rectangular steel blocks of a width of 6 mm are inserted between the specimen and the jaws. Typical EME and AE response waveforms appear not to differ from each other for either of the loading methods. However, a significant difference is observed in the frequency distribution of the time lag of the acoustic signal behind the electromagnetic one. This fact results from the difference in the distance between the crack generation point and the AE pickup device location for the two loading methods. This result is in a good agreement with the theoretic model prediction.
