In this paper the mechanical properties of commercial magnetorheological elastomer samples are experimentally characterized using compression and shear test rigs developed in-house. The test rigs are designed to provide a continuous magnetic field to the samples during dynamic testing. The magnetic field imposed on the samples is measured in real-time using a Hall effect sensor. In the experimental tests, the magnetorheological elastomer specimens are subjected to cyclic loading at various frequencies and magnetic field strengths. The results show an increase in stiffness and damping as the magnetic field increases.
