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.

二氧化钛纳米晶须电流变液的流变分析

摘要 了解电流变 (ER) 流体的屈服应力不仅对于开发先进的 ER 材料而且对于它们的工程应用都很重要。本研究基于提出的通用屈服应力函数，重新分析了输入电场下二氧化钛纳米晶须和二氧化钛纳米颗粒基 ER 悬浮液的动态屈服应力。通过推导出的临界电场值，通过按比例缩放的通用屈服应力函数将实验数据很好地绘制成一条线，该值将电场相关屈服应力区域与具有 2.0 的极化机制的斜率为 1.5 的斜率区分开来。
