The present paper focuses on the determination of effective magneto‐mechanical properties of magnetostrictive composite materials in consideration of their microscopic morphologies. For this purpose, a homogenization procedure involving a two‐scale transition is applied, where representative volume elements ( ${\cal RVE}$ s) on the microscopic level are used. In order to obtain characteristic non‐linear and hysteretic magnetization and magnetostrictive strain curves, we implemented a dissipative material model into the homogenization framework.
