Yield Stress Fluids Slowly Yield to Analysis
Science, 2009The behavior of a type of complex fluid (exemplified by mayonnaise and concrete) can depend on the sample's flow history.

Coiling of yield stress fluids
Physical Review E, 2011We present an experimental investigation of the coiling of a filament of a yield stress fluid falling on a solid surface. We use two kinds of yield stress fluids, shaving foam and hair gel, and show that the coiling of the foam is similar to the coiling of an elastic rope.

Electrorheological Fluids and Magnetorheological Suspensions, 2007
Recent experimental as well as theoretical investigations have shown that the formation of structures of magnetic nanoparticles has significant influence on the behaviour of ferrofluids. The dependence of this structure formation on the magnetic field strength and shear stress applied to the fluid leads to strong changes of the viscosity and to the ...

Helical Locomotion in Yield Stress Fluids
Physical Review Letters, 2023We report three stages for locomotion of a helical swimmer in yield stress fluids. In the first stage, the swimmer must overcome the material's yield strain to generate rotational motion. However, exceeding the first threshold is not sufficient for locomotion.

The role of plasma in the yield stress of blood
Clinical Hemorheology and Microcirculation, 2023BACKGROUND: Yielding and shear elasticity of blood are merely discussed within the context of hematocrit and erythrocyte aggregation. However, plasma might play a substantial role due its own viscoelasticity.

Journal of Non-Newtonian Fluid Mechanics, 2018
Abstract Yield stress materials are known to possess a certain threshold property, a strength , that must be overcome in order for flow to occur. This strength is commonly conceived as a scalar representation of the stress tensor at the yielding point, here called the yield stress tensor .

Wicking with a yield stress fluid
Journal of Physics: Condensed Matter, 2008This work presents an experimental investigation of the flow of a model yield stress fluid (yield stresses between 5 and 21 Pa) driven by capillarity in horizontal glass tubes with diameters ranging from 0.46 to 1.5 mm. It is shown that the liquid penetration stops after typically a few centimeters. The results disagree with a simple model based on the

On the yield stress of nanocrystals
Journal of Materials Science, 1993A generalization of the Hall-Petch relationship is proposed. The generalized relationship takes account of the contributions from intergrain sliding, generation of lattice dislocations, and influence of disclination-like defects. From this approach, a critical size corresponding to a maximum of the Hall-Petch size dependence is obtained.

Advances in yield stress measurements for chocolate
2017Chocolate (a cocoa dispersion), can be defined as a concentrated suspension made up of solid particles, such as sugar, cocoa powder, milk powder, etc., dispersed in a Newtonian liquid, generally cocoa butter. The rheological properties of this matrix are largely influenced by type and quantity of ingredients and processing techniques.
