Abstract
To determine the relationship between the stress-strain state induced by bending and several magnetic parameters, a laboratory three-point bending test was performed, and measurements were made during the test without removing the load using DIUS-1.21M instrument. The load at which plastic deformation started in the specimen was determined. Graphs of dependence of coercive force, residual magnetic induction and hysteresis loop area on the applied load were plotted. It is revealed that elastic bending leads to a monotonic drop in the coercive force and hysteresis loop area and to an increase in the residual magnetic induction. Elastic-plastic deformation of the beam leads to a strong decrease in the residual magnetic induction, but for an unambiguous assessment of the stress-strain state under a load up to 20 kN, a multi-parameter magnetic testing is required.
