Abstract :
A magneto-mechanical static modeling of ferromagnetic particle based on minimization of an energy function is presented. This modeling is made of a conjugate gradient method coupled with finite-element method for the mechanical problem resolution. Two-dimensional computational results highlighting the influence of magneto-mechanical coupling on the magnetic microstructure and behavior are reported.
