Název v původním jazyce

Experimental study of electromagnetic emission signals generated by crack generation in composite materials

Popis výsledku v původním jazyce

The formation of a crack is accompanied by the generation of an electromagnetic field. A differential equation was derived and solved to describe the transformation of the field parameters into an electric signal, provided capacitive sensors are used. Inthe next stage, an analysis of spurious external electromagnetic and acoustic fields was carried out and measures to suppress their effects were designed. The issue of amplifying extremely low electromagnetic signals generated during the crack formationwas dealt with, too. The mentioned analyses resulted in the design of a method to detect and evaluate electromagnetic emission (EME) signals and acoustic emission (AE) signals, which accompany mechanical stressing of materials and structures. Based on the results of such analyses, an automated double-channel measuring apparatus was used for signal data acquisition, saving and processing. The operation of the apparatus was successfully tested by processing a large set of measurement resu
