Multiphysics modeling of magnetoelectric composite disks by a 2D axisymmetric finite element approach

Abstract

A 2D axisymmetric finite element multiphysics model is proposed to study magnetoelectric composite disks. This modeling approach includes a nonlinear magneto-elastic model to replicate the behavior of magnetostrictive materials under static conditions. Additionally, it offers a harmonic regime resolution that considers frequency dependence, including the implicit inclusion of eddy currents in the formulation, as well as electrical load. To validate the model, simulation results regarding the dependence of the static magnetic field and frequency are presented and compared with experimental measurements from literature.
