The effect of shear rate on the reduction in shear stress of electrorheological fluids made from blending of low and high conductivity particles was studied. It was found that while the blend composition corresponding to the dip in shear stress does not depend on the shear rate, the relative magnitude of the dip does depend on the shear rate. At higher shear rates the dip became less pronounced. This behavior cannot be explained by the usual Bingham fluid model, but can be interpreted if we assume that the structures causing the shear resistance change with shear rate.
