Effect of punching and stress concentrations on mechanical behaviour of electrical steels

ArcelorMittal supplies advanced mechanical and magnetic material data for its iCARe
^TM
line of electrical steels to enable customers to optimise the design of their e-machines. This paper gives an overview of the experimental methodologies to assess the effect of stress concentrations and punched edges on the fatigue behaviour of thin gauge electrical steel sheets. The link between the mechanical properties and the microstructural and metallurgical features of the different materials is discussed.
