Resumen
It was reported that under the simultaneous stimulus of an electric field and shear, the particles in an ER fluid form lamellar formations in the direction of shear (adhered to one of the electrodes) which may be responsible for the ER activity more than the strength of the chains. In this way, it would be expected that the shear stress should change consistently with the morphology of the formations. In this work we studied the effect of shearing time, electric field strength and shear rate on the shear stress. We suggest that changes on shear stress with time are due to changes of the morphology of the lamellar formations. 15 6-7 695 703 Filisko, F.E., ER suspensions with ER active matrix liquids (1998) Proceedings of the 6th International Conference on Electro-Rheological Fluids, Magneto-Rheological Suspensions and Their Applications, pp. 5-11. , edited by M.
