Rheological behavior of electrorheological fluid (ERF) under an electric field is investigated experimentally. Structural strengthening and viscoplastic characteristics are evaluated at different intensities of the electric field and various concentrations of solid phase in ERF under its deformation in the system of disk parali el surfaces. An increase of the first difference of normal stresses is found at the increase of intensity of the electric field applied, and also its change in time. Furthermore the sign of normal stresses is changed depending on the magnitude of the electric field and deformation
