Journal ArticleDOI
Aging and solid or liquid behavior in pastes
TL;DR: In this article, the authors carried out systematic creep tests after different times of rest and over sufficiently long times with pasty materials of various internal structures in a Couette geometry and showed that for a stress below the yield stress these materials remain solid but undergo residual, irreversible deformations over long time which exhibit some trends typical of aging in glassy systems.
Journal ArticleDOI
Macroscopic vs. local rheology of yield stress fluids
TL;DR: In this article, the authors measured the local flow characteristics of a Carbopol gel in a Couette geometry under different inner cylinder rotation velocities and deduced the local, steady-state, simple shear, constitutive equation of the material within a relatively wide range of shear rates.
Journal ArticleDOI
Rheopexy and tunable yield stress of carbon black suspensions
TL;DR: In this paper, it was shown that a carbon black suspension exhibits a viscosity bifurcation effect around a critical stress along with rheopectic trends, i.e., after a preshear at a given stress the fluid tends to accelerate when submitted to a lower stress.

A Study of Dam Break Wave of Thixotropic Fluid: Bentonite Surges down an Inclined plane
TL;DR: In this paper, a study of dam break wave with thixotropic fluid is presented, which is the first theoretical analysis combining the basic principles of unsteady flow motion with the Saint-Venant equations.
