Modeling of Magneto-Mechanical Coupling Using Magnetic Volume Integral and Mechanical Finite-Element Methods
Résumé
The magneto-mechanical coupling with deformable bodies is studied using different numerical methods for both physics. The
magnetic behavior is considered linear and without magnetostrictive effects; then equations of the magneto-mechanical coupling can
be solved separately. A volume integral method using the magnetic scalar potential formulation is used. This method is particularly
well suited to compute fields without meshing the air domain. A local application of the virtual work principle, adapted to the
integral formulation, is used to compute the nodal magnetic force distribution at the origin of the magneto-mechanical coupling with
deformable bodies. An advantage of this approach is that the same mesh can be used by both methods during the resolution steps.
