Design and testing of magnetorheological elastomer ( MRE) for vibration mitigation

Magnetorheological elastomer (MRE) is widely known as the class of smart materials which contained micron-sized ferromagnetic particles that can reversibly tune the mechanical properties of damping and stiffness coefficient respectively in the presence of magnetic field. However, the current MR tech...
