Thixotropy of soft clay: A review
, 2021Thixotropy of soil is, after softening by remolding, a process of time-dependent return to a harder state under constant water content and constant volume conditions.

New insights on carbon black suspension rheology—Anisotropic thixotropy and antithixotropy
Journal of rheology, 2022We report a detailed experimental study of peculiar thixotropic dynamics of carbon black (CB, Vulcan XC-72) suspensions in mineral oil, specifically the observation of sequential stress increase then decrease at a fixed shear rate in a step-down test. We

Numerical Study of the Effect of Thixotropy on Extrudate Swell
Polymers, 2021 The extrusion of highly filled elastomers is widely used in the automotive industry. In this paper, we numerically study the effect of thixotropy on 2D planar extrudate swell for constant and fluctuating flow rates, as well as the effect of thixotropy on

Thixotropic spectra and Ashby-style charts for thixotropy
Journal of rheology, 2022There is no universal model for thixotropy, and comparing thixotropic effects between different fluids is a subtle yet challenging problem. We introduce a generalized (model-insensitive) framework for comparing thixotropic properties based on thixotropic

Thixotropy and rheological hysteresis in blood flow.
Journal of Chemical Physics, 2022Hemorheology is known to be a major diagnostic tool for many blood-altering diseases. While hemorheological measures of blood, such as the general flow curve, shear-thinning behavior, and its yield stress, are much more studied in detail, thixotropic ...

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.

Abstract A rotary displacement servo has been used to apply in-plane torques in vivo to an annulus of human skin between a driven disc and fixed guard ring. Using the servo, skin on the forearms of 44 normal healthy individuals was studied with a series of rotational displacements. A trapezoidal displacement vs time waveform was employed to provide
