A review of thixotropy and its rheological modeling

RG Larson, Y Wei - Journal of Rheology, 2019 - pubs.aip.org
We review thixotropy, its attributes, and accompanying rheological phenomena, such as
yielding, hysteresis in shear-rate ramps, the influence of rest time and viscosity bifurcation …

Distinguishing thixotropy from viscoelasticity

M Agarwal, S Sharma, V Shankar, YM Joshi - Journal of Rheology, 2021 - pubs.aip.org
