Abstract :
This paper presents a method for computing the deformation of ferromagnetic material due to magnetic forces and magnetostriction by using the finite-element method. In particular, the two-dimensional case, viz. the analysis of stresses and deformation in electrical steel sheet, is discussed. The experimental determination of the magnetoelastic properties is presented as well.
