In this work we present the modular construction and FEM implementation of a material model for magnetorheological elastomers (MRE) that is firmly rooted in micromechanics and performs well against experimental data. Keeping in mind the composite nature at the microscale, we develop a constitutive formulation based on a multiplicative magneto‐mechanical split of the deformation gradient. We consider both Lee‐ and Clifton‐type right and left decompositions. In contrast to other recent formulations [6], this general approach allows the use of highly advanced micromechnically‐based network models for polymers such as [4] and [5] in a modular format and to extend its application for coupled magnetomechanical response.
