Empirical modelling of non-Newtonian fluids exhibiting non-monotonous shear viscosity function
The models presented enable description of non-monotonous course of shear viscosity function against shear rate (stress) and apart from it they take into account possible existence of a yield stress for viscoplastic behaviour

Non-regular Tangential Behaviour of a Monotone Measure
We give an example of a closed set A in the plane such that the one-dimensional Hausdorff measure restricted to A is a 1-monotone measure with non-unique and non-conical tangent measures at a point. The example is related t...

On the modelling of non-monotonous viscosity describing feedstock behaviour in powder injection moulding
Feedstocks used in the process of powder injection moulding characterized by the flow of highly filled (60 vol.%) compound into a mould cavity, sometimes exhibit non-monotonous flow behaviour of viscosity in dependence on s...

On non-monotonous behaviour of shear-viscosity function.
The aim of this contribution is to propose a new phenomenological model enabling description of non-monotonicity of shear-viscosity function for rheologically complex fluids. The applicability of this model is discussed with the emp...

Phenomenological modelling of non-monotonous shear viscosity functions
The aim of this paper is to present a new phenomenological rheological model suitable for the description of a wide class of viscoelastic fluids. Classical phenomenological models predict the relation shear viscosity vs. shear rate (or shear stress) ...

Application of a 6-parameter empirical model describing non-monotonous shear viscosity function
A new 6-parameter empirical model is applied to a description of non-Newtonian flow situations when shear viscosity function in dependence on shear rate or shear stress exhibits either monotnous or non-monotonous behavi...

Modelling of non-monotonous course of shear viscosity
A number of parameters appearing in the 'classical' empirical constitutive equations usually oscillate between two and five. With the onset of new rheologically more complex materials exhibiting non-monotonous behaviour of ...
