A Finite Element based strategy is proposed for the evaluation of magnetic permeability for the equivalent homogenized material of a magnetic shielding mortar containing ferromagnetic particles. The representation of the composite mixture is done by using elements of the mesh as 3-D inclusions. A statistical analysis is performed on thousands of meshes representing the same sample geometry, with different inclusions distribution. The homogenization process is posed in form of a non-linear inverse problem. To solve it, a powerful parallel algorithm based on swarm intelligence is used. The obtained results are validated through an experimental setup.

Abstract
A Finite Element based strategy is proposed for the evaluation of magnetic permeability for the equivalent homogenized material of a magnetic shielding mortar containing ferromagnetic particles. The representation of the composite mixture is done by using elements of the mesh as 3-D inclusions. A statistical analysis is performed on thousands of meshes representing the same sample geometry, with different inclusions distribution. The homogenization process is posed in form of a non-linear inverse problem. To solve it, a powerful parallel algorithm based on swarm intelligence is used. The obtained results are validated through an experimental setup.
