New analysis of yield stress on giant electrorheological fluids

A new universal yield stress scaling equation is proposed to accurately model experimental data for giant electrorheological (GER) fluids. This new equation expressed in modified Bessel function predicts both regions of polarization effect predominant in the low electric field strength applied and polar molecule-dominating GER behavior, as well as collapses the experimental data of yield stress in a single line for a broad range of electric field strengths.
