Abstract

A magnetorheological elastomer (MRE) is fabricated, with Fe microparticles in the shape of chains, parallel among themselves and parallel with the cylindrical bar generator ( 36 62 mm2). For constant values of the moment of force , we measure the rotation angle of the cylindrical bar in longitudinal magnetic field with intensities in the range 0  H(kA/m)  200. For the cylindrical bar with undefined flat sections, the turning angle is also determined as a function of H, for constant values of . It is shown that the rigidity of MRE is increased under the influence of the longitudinal magnetic field. The obtained results are presented and discussed..
