Abstract

Understanding yield stress of electrorheological (ER) fluids becomes important for not only development of advanced ER materials but also their engineering applications. This study reanalyzed dynamic yield stresses of both titanium dioxide nano-whisker- and titanium dioxide nano-particle-based ER suspensions under an input electrical field, based on the universal yield stress function proposed. The experimental data was plotted well to a single line by the scaled universal yield stress function via a deduced critical electrical field value which divides electric field dependent yield stress region with a slope of 1.5 from that with 2.0 of polarization mechanism.
