To use magnetic methods to study the effects of stress on the properties of ferromagnetic materials it is necessary to have a reliable model of the magnetic hysteresis behaviour of the material. The effects of stress on the various parameters defining hysteresis can then be determined. Later these parameters may be calculated from hysteresis measurements in order to evaluate the stress. The situation is likely to be further complicated by such factors as residual microstrain in the sample and if the elastic limit is exceeded, by plastic deformation. Nevertheless the outlines of the magnetic method given show how it can be used for nondestructive inspection of stress.
