Abstract

The rapid change in viscosity of magnetorheological (MR) and electrorheological (ER) fluids subjected to a magnetic or an electric field, respectively, has attracted the attention of many researchers. However, as MR fluids show higher yield stress than ER fluids, they have merited more attention during the last few years. In this paper we present an over-view of magneto- and electrorheological fluids, their basic properties, behavior under different flow types and their uses in fluid power systems, among others.

Keywords: magnetorheological fluids, electrorheological fluids, smart materials, fluid power
