Abstract
Research was carried out with a view to developing a methodology and algorithms for the determination of the stress-strain state of a ferromagnetic component based on measurements of magnetic properties. The aim of the testing was to define the stress-strain state, both as the effect of active stresses resulting from load and after unloading. The studies involved an analysis of changes in the residual magnetic field (RMF) and in the Barkhausen effect caused by the magnetic field (MBE). Good quantitative relationships between active stresses and the number of counts, which is one of the parameters that describe the MBE quantitatively, were found. It was also found that the MBE number of counts could be used as a diagnostic signal to develop correlations for the evaluation of the hardness of some ferromagnetic steels. A method for the evaluation of the first order residual stress in ferromagnetic steels based on residual magnetic field measurements was presented. The values and distributions of the gradients of the RMF components show a good correlation with the values and distributions of residual stresses, both qualitatively and quantitatively. It is found that it is possible to develop the dependence between the RMF gradients and the first order residual equivalent (von Mises) stresses arising in the notch effect area.
