Abstract

The study addresses experimental characterization of magnetorheological elastomers (MRE) with six different particle loadings under various magnetic field intensities. The MREs consisted of spherical iron particles, 6 to 10 μm in diameter, ranging from 0.25 to 30% weight fraction, cured in a nonmagnetic silicone rubber host elastomer. Mechanical properties of MREs such as equivalent viscous damping and complex stiffness were experimentally determined by using an Instron material testing machine with a magnetic cell. The effects of weight fraction of particles, displacement excitation frequencies, and pre-strain on the field-dependent properties of MREs were experimentally evaluated.
