Description
  • Cracks creation is accompanied by electric charge redistribution due to loosened chemical bonds. Electric charges on crack walls create dipole moments. Crack wall vibrations produce time dependent dipole moments and, consequently, electric and magnetic fields are generated. An electric signal is induced on metal electrodes. Information about the crack wall vibration was obtained from this signal analysis. For crack lengths below 1 mm the respective electrical signal has a frequency of over 2 MHz. In this paper the frequency analysis was performed in a frequency band of up to 5 MHz.
