Strong magnetomechanical FE coupling using local magnetostriction forces

The magnetic material's deformation caused by magnetostriction is represent ed by an equivalent set of mechanical forces, giving the same deformation t o the material as magnetostriction does. This is done in a way similar to h ow thermal stresses are usually incorporated into stress analysis. The resu lting magnetostriction force distribution can be superposed onto other forc e distributions, like the magnetic force distribution. These two force dist ributions are the key ingredients of a numerically strong coupling of the m agnetic and the mechanical finite element systems.
