Tuning colloidal gels by shear.
Using a powerful combination of experiments and simulations we demonstrate how the microstructure and its time evolution are linked with mechanical properties in a frustrated, out-of-equilibrium, particle gel under shear. An intermediate volume fraction colloid-polymer gel is used as a model system, allowing quantification of the interplay between interparticle attractions and shear forces. Rhe...
متن کاملYielding of colloidal gels under steady and oscillatory shear
Submitted for the MAR15 Meeting of The American Physical Society Yielding of colloidal gels under steady and oscillatory shear GEORGE PETEKIDIS, ESMAEEL MOGHIMI, NICK KOUMAKIS, IESLFORTH, FORTH TEAM — The structural and rheological properties of intermediate volume fraction colloid polymer gels are examined during and after steady and oscillatory shear flow using rheometry, confocal microscopy,...
متن کاملColloidal gels under shear: Strain rate effects
Attractive colloidal particles are trapped in metastable states such as colloidal gels at high attraction strengths and attractive glasses and high volume fractions. Under shear such states flow via a two step yielding process that relates to bond and cluster or cage breaking. We discuss the way the structural properties and related stress response are affected by the shear rate. At low rates c...
متن کاملStructural change and dynamics of colloidal gels under oscillatory shear flow.
The dynamics and rheological behavior of colloidal gels under oscillatory shear flow have been studied by using the Brownian dynamics simulations. The dynamics is studied under the oscillatory shear of small, medium, and large amplitudes. In the small amplitude oscillatory shear (SAOS) regime, the colloidal gel retains a rigid-chain network structure. The colloidal gel oscillates with small str...
متن کاملPredicting and assessing rupture in protein gels under oscillatory shear.
Soft materials may break irreversibly upon applying sufficiently large shear oscillations, a process whose physical mechanism remains largely elusive. In this work, the rupture of protein gels made of sodium caseinate under an oscillatory stress is shown to occur in an abrupt, brittle-like manner. Upon increasing the stress amplitude, the build-up of harmonic modes in the strain response can be...
