▎ 摘  要

Based on flow curve of graphene oxide coated polymeric microsphere based electrorheological (ER) fluid, model independent yield stress and shear rate, (gamma) over dot(tau), were determined using a Tikhonov regularization technique developed to solve the inverse problem of the shear rate in Couette flow viscometry. The model independent yield stress data were compared with that extracted from yield stress fluid models of Bingham plastic and Cho-Choi-Jhon (CCJ) used to fit the (gamma) over dot(tau) data. The agreement between model independent and Bingham yield stress was excellent, while the CCJ model yield stresses are generally slightly higher.
