Journal of Non-Newtonian Fluid Mechanics, 1979
Abstract The time-dependent behaviour associated with thixotropy rather than with viscoelasticity is discussed. The evolution of the concept is traced back and a generalized definition is accepted. Subsequently, the various experimental methods are considered with which meaningful measurements of thixotropy can be performed. The specific experimental

Thixotropy and Plasticity. I—The Measurement of Thixotropy
Journal of Rheology, 1932Thixotropy is a reversible sol-gel transformation in which a gel can be liquefied, and thus changed to the sol condition, by mechanical disturbance—such as shaking or stirring—and after agitation ceases will, with time, again revert to the gel condition.

Journal of Non-Newtonian Fluid Mechanics, 1997
Abstract The ensuing mechanical response to stressing or straining a structured liquid results in various viscoelastic phenomena, either in the linear region where the microstructure responds linearly with respect to the stress and strain but does not itself change, or in the nonlinear region where the microstructure does change in response to the ...

Thixotropy of Semisolid Metals
MRS Proceedings, 1999AbstractUnderstanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is modeled using conservation equations and the Herschel-Bulkley fluid model.

Abstract Thixotropy was observed on the gels formed by the addition of the suitable amounts of cupric chloride, barium chloride, lead nitrate, calcium chloride, cadmium sulfate, zinc sulfate and nickel sulfate to the solutions of sodium alginate.

Zur Thixotropie von Bentonitsuspensionen
Kolloid-Zeitschrift, 1949Die Fliesgrenzen A von Bentonitsuspensionen wurden in reinem Wasser und bei Zusatz von Elektrolyten in ihrer Zeitabhangigkeit bei verschiedenen Temperaturen bestimmt. Es ergab sich: 1. Die Endwerte der Fliesgrenze A∞ lassen sich fur verschiedene Bentonitkonzentrationen innerhalb des untersuchten Konzentrationsbereiches von 3 bis 7% durch eine ...

The author adopts the original Freundlich-Peterfi definition of thixotropy, that is the reversible isothermal gel/sol/gel/transformation induced by shear and subsequent rest. The criterion of a gel is the presence of a “Yield Value”, and that of a sol the absence of a “Yield Value”.

Thixotropy and Plasticity. III—The Effect of Thixotropy upon Plasticity Measurements
Journal of Rheology, 1932The first two papers of this series have dealt entirely with thixotropy, while this paper deals with plasticity as it is affected by the presence of thixotropy. Several rather revolutionary conclusions will be arrived at for which the experimental proof cannot as yet be considered adequate.
