The processes of formation and growth of an incipient crack in EI847 steel have been studied by uniaxial constant-load tension testing on an INSTRON-5982 tensile testing machine using scanning contact potentiometry. The nucleus was detected at the sample surface within the yield strength domain and was stably monitored based on the readings of apparatus under higher loads until the moment of destruction.
