Abstract

This work uses dynamic shearing experiments to examine S- (soft magnetic) and H- (hard magnetic) magnetoactive elastomers of four different types. The aligned materials had larger shear stiffness, and all materials but the unaligned H material displayed increased stiffness with magnetic field. All four types showed generally the same damping ratio with no strong trends across material types. We discuss these results in terms of shearing forces arising due to magnetic torques.
