摘要：

In the fabrication of soft magnetic composite materials, the iron powder particles are submitted to a high-pressure compaction process that should be considered in the modeling of magnetic hysteresis. This paper introduces a novel approach for modeling the stress-dependent magnetic hysteresis, based on the Stoner-Wohlfarth (S-W) model. Moreover, for determining the S-W particle equilibrium orientation directly, an extended S-W astroid method, which considering the stress effect, is presented. To verify this presented model, the magnetic hysteresis phenomenon of SOMALOY 500 are measured and simulated. The comparison between the two results shows that this model is feasible and effective, which can be applied to practical engineering.
