THE ROLE OF SUSPENSION STRUCTURE IN THE DYNAMIC RESPONSE OF ELECTRORHEOLOGICAL SUSPENSIONS

摘要: The dynamic response of electrorheological (ER) suspensions has received little attention relative to the effort devoted study steady shear response. We report on simulation and experimental investigations oscillatory ER suspensions, in particular focusing relationship between suspension structure rheological consider monodisperse polydisperse under linear deformation, as well nonlinear regime. Dimensional analysis equations motion predict that obeys a time-field strength superposition principle, which is confirmed by experiment. found exhibit sharp dispersion only broadened slightly polydispersity. Nonlinear deformation significantly broaden observed dispersion.
