Originální abstrakt
Cracks creation was studied by simultaneous measurement of electromagnetic (EME) and acoustic (AE) emission signals. This method can improve localisation of the crack position, cracks plane orientation and its dimension. On the faces of new created crack electric charges constitute electric dipole system and due to crack walls vibration an EME signal is detected with frequency 1-10MHz corresponding to crack length 0.1 to 1 mm. The second source of EME signal is later activated due to whole sample mechanical vibrations with a frequency given by sample boundary conditions in the range 50-500kHz.
