Measurement of the two-dimensional magnetostriction and the vector magnetic property for a non-oriented electrical steel sheet under stress

This paper presents the influence of mechanical stress on the two-dimensional (2-D) magnetostriction and the vector magnetic property for a non-oriented electrical steel sheet. A six-axial strain gauge is developed in order to measure the in-plane mechanical stress and the magnetostriction of the non-oriented electrical steel sheet. The vector magnetic property and 2-D magnetostriction under tensile and compressive stress are also measured. From the results, the difference in the vector magnetic property and 2-D magnetostriction due to the applied mechanical stress is obtained.
