Amorphous solids relax via slow molecular rearrangement induced by thermal fluctuations
or applied stress. Microscopic structural signatures predicting these structural relaxations …

Yield stress fluids (YSFs) display a dual nature highlighted by the existence of a critical
stress σ y such that YSFs are solid for stresses σ imposed below σ y, whereas they flow like …

Colloidal glasses are out-of-equilibrium in nature. When such materials are quenched from
a shear-melted state into a quiescent one, their structure freezes due to entropic caging of …

The rheology and microstructure of soft particle glasses during startup flow are studied using
three-dimensional particle dynamics simulations at different particle volume fractions and …

A combination of experiments and Brownian Dynamics simulations is utilized to examine the
mechanisms of yielding and flow in attractive colloidal glasses during start-up shear flow. In …

Densely packed soft microgels (pastes) behave as a yield-stress fluid. They act as soft
elastic solids with finite equilibrium shear modulus (G 0) below a critical stress (σc) whereas …

Hypothesis Soft microgel colloids can be densely packed since particle networks can
compress and interpenetrate. This evolution of the particle's internal structure associated …

In rheological experiments, the relationship between stress and strain is determined. In the
transient regime, this relationship may depend on which of these properties is applied and …

The rheological behaviors of yield stress fluids are commonly interpreted from the energy
perspective, yet this perspective has rarely been applied for waxy gel. In this study, we …

We investigated the mechanical properties of gels formed by silk fibroin and silk
fibroin/cellulose nanocrystal mixtures. Viscosity and linear viscoelasticity measurements …
