The relation between the physical parameters of nondestructive testing (coercive force, eddy current parameter, self-magnetic field, acoustic emission parameters) and the characteristics of real damage (relative damaged surface area, concentration criterion), which were estimated during the tension of grade 20 and 45 steel specimens with stress concentrators, is studied.
