Rheological complexity in simple chain models
The Journal of Chemical Physics, 2008Dynamical properties of short freely jointed and freely rotating chains are studied using molecular dynamics simulations. These results are combined with those of previous studies, and the degree of rheological complexity of the two models is assessed.

The theory of rheological models considers series and parallel combinations of lumped elements that are assumed to behave mechanically like the constituent phases of a material, but that, apart from this mechanical behavior, have nothing in common with the real medium. Usually, the elements are elastic springs, viscous dashpots, and dry-friction bodies.

Drumlin Formation: A Rheological Model
Science, 1966Drumlins are formed in a layer of boulder clay separating a glacier from certain types of terrain. Under certain conditions the large particles in the clay form a dilatant system. When flow in the separating layer is interrupted, part of the layer packs into an obstruction and the rest of the material flows around this obstruction, giving it a ...

Rheological models vs. homogenization
GAMM-Mitteilungen, 2011AbstractWe show that the outcome of the theory of homogenization is at variance with a classical engineering technique, that is widely used for constructing rheological models of mechanical materials (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Rheological models for xanthan gum
Journal of Food Engineering, 1996Abstract The rheological behaviour of xanthan gum was determined at various temperatures (20–100 °C) and concentrations (0·3–1·3%), and was found to be most adequately described by a power-law model. The effect of temperature on the viscosity followed an Arrhenius relationship, whereas the effect of concentration followed an exponential relationship.

Rheology is the science of the deformation and flow of materials. It deals with the theoretical concepts of kinematics, conservation laws and constitutive relations, describing the interrelation between force, deformation and flow. The experimental determination of the rheological behaviour of materials is called rheometry.

Rheological Models of Suspensions
1990Publisher Summary This chapter reviews the existing models of suspensions within a unified framework that aims to bridge parochial disciplinary fragmentation of the suspension theory. The chapter also discusses some specialized subdivisions into which suspension theory has branched.

Rheological models for gypsum plaster pastes
Rheologica Acta, 1988Shear stress and shear rate data obtained for gypsum plaster pastes were correlated by means of different rheological models. The pastes were prepared from a commercial calcium sulfate hemihydrate at various water/plaster ratios ranging from 100/150 to 100/190. The tests were performed at 25°C using a rotating coaxial cylinder viscosimeter.

Rheological Model of Pore Water
Journal of Rheology, 1985A rheological model of the flow of an aqueous electrolyte solution near a polar interface is presented, which is based on general equations of electrostatics and mechanics of an isotropic inhomogeneous continuum. The main purpose of the theory is to account for the consequences of an additional orientation of water molecules caused by the electrical ...
