要約(英語): Evaluation method of the magnetic properties of electrical steels under compressive stress along magnetizing direction using single sheet samples was studied. In this measurement, the friction due to retainer plates for applying normal pressure to prevent buckling should be considered. Experimentally, influence of the friction tended to be stronger with the increase in the pressure onto the retainer plate, and with the decrease in the stress along the magnetizing direction. Numerical analysis of mechanical stress indicated that the effects of friction coefficient and sheet thickness were significant. The method to revise the influence of the friction covering wide range of stress along the magnetizing direction was proposed. Furthermore, the effect of the normal pressure on the magnetic properties was evaluated and correction method to obtain true stress in magnetizing direction was studied.
