Abstract
Transient process of electrorheological (ER) fluids compressed between two parallel plates and applied a high square-wave voltage has been modeled based on transient shear strain constant and shear stress and experimentally verified. The transient compressive resistance is integrated from the pressure distribution at the middle plane between the plates. Employing transient shear strain constant derived from other experimental investigations of dynamic shearing of ER fluids to fit the tested compressive stress, good results have been obtained. The rising of compressive stress upon the sudden applying of an electric field showed to be governed by the experienced shear strain of the compressed ER fluid.Keywords
