Damping of magnetorheological elastomers

The damping property of magnetorheological (MR) elastomers is characterized by a modi¯ed dynamic mechanical-magnetic coupled analyzer. The in°uences of the external magnetic °ux density, damping of the matrix, content of iron particles, dynamic strain, and driving frequency on the damping properties of MR elastomers were investigated experimentally. The experimental results indicate that the damping properties of MR elastomers greatly depend on the interfacial slipping between the inner particles and the matrix. Di®erent from general composite materials, the interfacial slipping in MR elastomers is a®ected by the external applied magnetic field.
