Texture is an important property for most food products and is usually characterised by different rheological methods together with data from microstructural investigations. However, the correlation between results from rheological measurements and microstructural data is not always unambiguous. Therefore the demand of developing new types of rheological measurements as well as structural measu...

The theological parameters of a clay suspension can be used to evaluate particle-particle interactions. Although there have been many studies of the rheological behavior of suspensions of reference clays, only few studies were performed with suspensions of mixed clays, and the rheological properties of these suspensions are not yet fully understood. The length-to-width ratio of some soil clays ...

A prescription of model dental anti-inflammatory gels has been worked out on the base of cellulose derivatives with the content of saccharic alcohols: xylitol and sorbitol. The effect of saccharic alcohol on rheological parameters (extensibility and viscosity) of the produced gels was tested. Taking into account application, the most beneficial results of rheological tests were obtained for gel...

We study theoretically the onset of shear banding in the three most common time-dependent rheological protocols: step stress, finite strain ramp (a limit of which gives a step strain), and shear startup. By means of a linear stability analysis we provide a fluid-universal criterion for the onset of banding for each protocol, which depends only on the shape of the experimentally measured time-de...

We review recent work done on the rheology of thermosensitive suspensions. These systems consist of aqueous suspensions of coreshell particIes having asolid polystyrene core and a shell of thermosensitive crosslinked poly(N-isopropylacrylamide) (PNIPA). In cold water the thermosensitive PNIPA-network is swollen leading to a high effective volume fraction of the particles in suspension. Approach...

A stochastic rheological model for the calculation of polymer stress in polymeric fluids is developed and evaluated. The model is microscopic-based and combines aspects of reptation, modified network and continuum models. A concentrated Polyisobutylene (PIB) solution is simulated for material functions in various rheometric flows. Comparisons made with available experimental data shows that the...

An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...
