The influence of the magnetic field on the elastic properties of anisotropic magnetorheological elastomers

This paper deals with the process of achievement of anisotropic magnetorheological elastomers (MREs), based on silicone rubber and iron nanoparticles. Plane capacitors are manufactured with MREs. The capacity C of the plane capacitors is measured as function of the intensity H of the magnetic field. By using the approximation of the dipolar magnetic moment and the ideal elastic body model, respectively, the tensions and deformations field and respectively the elasticity module of MREs function of H have been determined, for magnetic field values of up to 1000 kA/m. The obtained results are presented and discussed.
