Abstract :
A non linear homogenization approach, based on 3D edge finite elements method, is used to determine the equivalent electromagnetic properties of the Soft Magnetic Composites (SMC). A new geometry generation algorithm is introduced to take into account the material density, the randomized size and location of the SMC particles and the insulation layer around the particles. A modified Preisach hysteresis model associated with a new analytical Lorentz function is developed to calculate the homogenized hysteresis loops from intrinsic properties of its constituents.
