Original abstract

When a stress is applied to the solids (rocks or tiles) cracks creation can be detected by signals of an acoustic and electromagnetic emission. The recorded electric signal is superposition of crack walls "self" vibration and vibration due to an ultrasonic wave. The simultaneous investigation of acoustic and electromagnetic emission signals enable us to localise the crack position in solids.
