Effect of compressive stress on hysteresis loss and magnetostriction of grain oriented Si–Fe sheets
2003
Changes in hysteresis loss and magnetostriction λ due to compressive stress σ are discussed for grain oriented Si–Fe sheets. L and T samples are prepared for each kind of sheets, where the longitudinal direction of the L/T sample is parallel/transverse to the rolling direction of the sheets. Hysteresis loss of all samples increases owing to compressive stress σ, and the increased value is in proportion to λσ. The proportional ratio between them varies depending on the conditions of the sample and measuring maximum flux density.
