Rheological properties of human saliva [PDF]

Archives of Oral Biology, 1988
From measurements with a Couette-type viscometer provided with a guard ring it was shown that at the saliva-air interface a protein layer is adsorbed. Measurements of the surface shear modulus of this layer on saliva of 7 healthy subjects were performed at a frequency of about 70 Hz and a temperature of 25 degrees C.

Rheological properties of aging thermosensitive suspensions [PDF]

Physical Review E, 2007
Aging observed in soft glassy materials inherently affects the rheological properties of these systems and has been described by the soft glassy rheology (SGR) model [S. M. Fielding, J. Rheol. 44, 323 (2000)]. In this paper, we report the measured linear rheological behavior of thermosensitive microgel suspensions and compare it quantitatively with the

Rheological Properties of PVDF Solutions [PDF]

Journal of Siberian Federal University. Mathematics & Physics, 2021
The rheological properties of polyvinylidene fluoride (PVDF) solutions in Nmethylpyrrolidone were studied using the rheometric method. It was shown that the viscosity of polymer solutions decreases non-linearly with increasing temperature. The viscosity of the N-methylpyrrolidone used as solvent remains practically unchanged.

Construction of 3D Creep Model of Landslide Slip-Surface Soil and Secondary Development Based on FLAC3D

Advances in Civil Engineering, 2020
Landslide deformations have predictable rheological properties, but, when using finite element analysis, only the elastoplastic constitutive equation of soil is considered. Soil creep properties are not considered, often rendering inaccurate results.
