Original Abstract

Our study is focused on the use of spectral characteristics of electromagnetic emission signals for damage assessment of mechanical loaded composite materials. We have developed a methodology for evaluation of the power spectral density of the crack electric dipole moment waveform based on the measured voltage at the capacitance sensor measurement circuit output. The obtained characteristics were studied in dependence on the applied force for the various loading conditions.
