"The aim of this contribution is to discuss various hitherto published approaches how to model phenomenologically non-monotonous dependence of viscosity on shear rate or shear stress. As two basic criteria there are chosen a number of model parameters and their physical interpretation. Non-uniqueness of the choice of a value corresponding to the location of the initial Newtonian plateau is demonstrated. This problem is roughly adequate to that how to determine a yield stress for viscoplastic materials." . "Melbourne [AU]" . "1"^^ . "X1-X5" . . "603150" . . . .
