ABSTRACT:
The moment of beginning of fracture in breaking strength tests of ferromatic samples (7) is detected by the spreading of a magnetic field out of the incipient crack in the magnetized sample by means of a magnetic probe (23). Until the beginning of the crack, the magnetic field runs through the magnetized sample. The voltage induced in the magnetic probe at the moment the crack starts is used to stop a time measuring counter which was reset and turned on at the beginning of the stressing of the sample.
