A theoretical framework underlying an accelerated testing method and its application to composites under constant strain rates and fatigue loading

open access: yesScience and Engineering of Composite Materials, 2022
A theoretical framework that underlies an accelerated testing method for unidirectional (UD) composites is proposed in this article, based on the continuum damage mechanics and time–temperature superposition.

A Lattice Boltzmann study of the effects of viscoelasticity on droplet formation in microfluidic cross-junctions

open access: yes, 2016
Based on mesoscale lattice Boltzmann (LB) numerical simulations, we investigate the effects of viscoelasticity on the break-up of liquid threads in microfluidic cross-junctions, where droplets are formed by focusing a liquid thread of a dispersed (d ...

The Effect of Inkjet Ink Composition on Rheology And Jetting Behaviour [PDF]

open access: yes, 2009
This work presents recent results on the way linear and non linear viscoelastic properties of the fluids affect the jetting mechanism. Recent progress on quantitative characterising both high frequency linear (LVE) and non-linear (NLVE) viscoelasticity ...

Physical interpretation of initial conditions for fractional differential equations with Riemann-Liouville fractional derivatives

open access: yes, 2005
On a series of examples from the field of viscoelasticity we demonstrate that it is possible to attribute physical meaning to initial conditions expressed in terms of Riemann-Liouville fractional derivatives, and that it is possible to obtain initial ...

Quantifying the early-age viscoelastic properties of alkali activated slag concrete using repeated minutes-long creep tests

open access: yesRILEM Technical Letters
The early-age viscoelasticity of alkali-activated slag concrete (AASC) is critical for its early-age cracking proneness and long-term performance, particularly regarding creep and internal stress development. This study employs an innovative approach to

Rheological and microstructural study of concentrated sunflower oil in water emulsions stabilized by food proteins

open access: yesGrasas y Aceites, 2008
Droplet Size Distribution (DSD) and linear viscoelastic properties of concentrated o/w emulsions stabilized by different proteins (crayfish, gluten and soybean) have been studied. A typical behaviour of highly concentrated emulsions with a high degree of

Study of non-linear viscoelastic behavior of the human red blood cell [PDF]

open access: yes, 2018
The non-linear behavior of human erythrocytes subjected to shear stress was analyzed using data series from the Erythrocyte Rheometer and a theoretical model was developed.

Relationship between rheology and structure of interpenetrating, deforming and compressing microgels

open access: yesNature Communications, 2019
Thermosensitive microgels are widely studied polymer-colloid hybrids but their interactions and packing are still not fully understood. Here, the authors study the linear viscoelasticity of dense microgels and analyse the local particle structure and ...
