Abstract
The paper addresses the topic of residual stress in magnetic behaviour of the ferromagnetic materials. Carbon steel parts are submitted to several stress loads and the magnetic behaviour is collected at several operating points. After stress load, the hysteresis data are measured and illustrate a complex behaviour in hysteresis morphology where a big belly is observed near coercive field and a short neck in maximum induction zone. In order to describe the B-H curves, a modified Arctangent model is proposed. A comparison between experiments and model signals show a very good accuracy.
