On the Nature of Flow Curve and Categorization of Thixotropic Yield Stress Materials [PDF]
, 2022 Thixotropy is a phenomenon related to time dependent change in viscosity in presence or absence of flow. The yield stress, on the other hand, represents the minimum value of stress above which steady flow can be sustained. In addition, the yield stress of a material may also change as a function of time. Both these characteristic features in a material

Interlayer bonding investigation of 3D printing cementitious materials with fluidity retaining polycarboxylate superplasticizer and high dispersion polycarboxylate superplasticizer [PDF]
Construction and Building Materials (2022), 2021 Proposed special requirements exist for the rheological properties and time varying characteristics of 3D printing cementitious materials (3DPC). In this study, high dispersion polycarboxylate superplasticizer (HD PC) and fluidity retaining polycarboxylate superplasticizer (FR PC) were used to control the rheological behaviors of 3DPC.

Thixotropy and dilatancy [PDF]
Clay Minerals, 1966 AbstractThe matric potential of water in gels of five-sixths neutralized aluminium montmorillonite (bentonite) and aluminium kaolinite changes during periods of shear and periods of rest. Shear increases the potential of water in bentonite gels, and in kaolinite gels containing little water, but decreases the potential in kaolinite gels containing more

Duncan–Chang E-υ Model Considering the Thixotropy of Clay in the Zhanjiang Formation
Sustainability, 2022 The clays of the Zhanjiang Formation in the coastal area of Beibu Gulf of China are thixotropic, and the existing constitutive relationship models relevant for clay are incapable of accurately simulating their stress–strain relationships.

A Comparative Study of Platysmal Myoneurectomy With Variations of Selective Neurectomies in Post-Facial Palsy Synkinesis. [PDF]
MicrosurgeryABSTRACT Synkinesis is a distressing sequela of facial palsy. The main treatment for this condition has been Botulinum toxin injections. However, more recently, selective neurolysis/neurectomies have shown promise, with some variations in practice evolving over time. A clinical review of practice was performed on sixty‐eight patients (n = 68) with Bell'

Impact of thixotropy on flow patterns induced in a stirred tank : numerical and experimental studies [PDF]
, 2008 Agitation of a thixotropic shear-thinning fluid exhibiting a yield stress is investigated both experimentally and via simulations. Steady-state experiments are conducted at three impeller rotation rates (1, 2 and 8 s−1) for a tank stirred with an axial ...

A review of thixotropy and its rheological modeling
Journal of rheology, 2019 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, and the prevalence and importance of thixotropy in common fluids.
