In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable of predicting the actuation behavior of hard- and soft-magnetic MREs.

This work simulates the bending of the beams due to combined magnetostatic and elastic forces. The primary problem COMSOL addresses is the 2-way coupling between elastic deformation and the magnetic field interactions.
