Abstract

The formation and development of cracks in the sample of ferromagnetic material in magnetized condition were researched. It was shown that magnetic state of material of friction surface most substantially influences the process of its brittle or quasibrittle fracture if cracks open perpendlcularly to magnetization vector. The criterion of unintentional growth of crack in magnetic field was established.
