Abstract
The MTS biaxial testing machine is employed to fabricate specimens with different plastic deformations and fatigue damages. The four-terminal direct current potential drop method is employed to investigate the influence of plastic deformation/fatigue damage on the material conductivity property. The soft magnetic hysteresisgraph method is employed to investigate the influence of plastic deformation/fatigue damage on the material magnetic property. In this study, the correlation of material electromagnetic properties and the plastic deformation is investigated, and the mechanism is explained through microstructure analysis. Moreover, the influence of fatigue damage on the material electromagnetic properties is confirmed. Finally, the combined effect of plastic deformation and fatigue damage is also investigated through experiments.
