Subyield Dynamics in Yield-Stress Materials [PDF]

Physical Review Letters
The mechanical response of yield-stress materials below the yield point remains a subject of debate. Two of the most widely used constitutive models for these materials offer fundamentally conflicting views: one permits plastic flow at all stress levels, while the other assumes entirely recoverable viscoelasticity below yield.

How quarry waste limestone filler affects the rheological behavior of cement-based materials

Applied Rheology, 2021
The main objective of this work is to highlight experimentally the effect of quarry waste limestone fillers (LF) on the rheological properties of concrete. All mixtures were made with water-to-cement ratio (W/C) of 0.50.

THE EFFECT OF STIFFNESS OF THE LOADING SYSTEM ON DETERMINATION OF TENSILE CHARACTERISTICS FROM THE RESULTS OF SMALL PUNCH TESTS

Acta Metallurgica Slovaca, 2014
The assessment of the residual lifetime of critical components of industrial plants requires the knowledge of mechanical properties prior to operation, respecting all technological operations realized throughout the manufacture of the component, and the ...

No yield stress required: Stress-activated flow in simple yield-stress fluids

Journal of Rheology
An elastoviscoplastic constitutive equation is proposed to describe both the elastic and rate-dependent plastic deformation behavior of Carbopol® dispersions, commonly used to study yield-stress fluids. The model, a variant of the nonlinear Maxwell model with stress-dependent relaxation time, eliminates the need for a separate Herschel–Bulkley yield ...

Influence of Anaerobic Degradation of Organic Matter on the Rheological Properties of Cohesive Mud from Different European Ports

Journal of Marine Science and Engineering, 2022
The presence of clay-organic flocs in cohesive mud results in a complex rheological behavior of mud, including viscoelasticity, shear-thinning, thixotropy and two-step yielding.

Yield stress discontinuity in a simple glass [PDF]

Physical Review B, 2006
Large scale molecular dynamics simulations are performed to study the steady state yielding dynamics of a well established simple glass. In contrast to the supercooled state, where the shear stress, $σ$, tends to zero at vanishing shear rate, $\gammadot$, a stress plateau forms in the glass which extends over about two decades in shear rate.
