Viscoplasticity is characterized by a yield stress, below which the materials will not deform
and above which they will deform and flow according to different constitutive relations …

We examine and compare five constitutive models, which have been recently proposed to
describe the behavior of elasto-visco-plastic fluids. The comparison is performed in simple …

We present a comparative experimental study of unsteady laminar flows of a yield stress
shear thinning fluid (Carbopol® 980) in two distinct configurations: a parallel plate …

The question of whether Carbopol gels always behave as “model” yield stress material is
addressed experimentally. Prompted by several simple hydrodynamic experiments …

We study the temporal stability of linear two-dimensional disturbances of plane Poiseuille
flow of a Casson fluid in a rigid parallel channel under the influence of a uniform magnetic …

Materials which exhibit elastic and yielding behavior are present in many industrial
processes including thin-film coating, oil extraction, manufacturing of consumer products …

Modal and non-modal stability analyses are performed for Poiseuille flow of a Bingham fluid
overlying an anisotropic and inhomogeneous porous layer saturated with the same fluid. In …

The ability to predict and/or control wall slip is a fundamental problem in the hydrodynamics
of yield stress fluids, which is poorly understood to date and has important applications in …

On the example of two-phase continua experiencing stress-induced solid–fluid phase
transitions, we explore the use of the Euler structure in the formulation of the governing …

We present a Gibbs random field model for the microscopic interactions in a viscoplastic
fluid. The model has only two parameters which are sufficient to describe the internal energy …
