On the Nature of Flow Curve and Categorization of Thixotropic Yield Stress Materials
Tulika Bhattacharyya, Alan R. Jacob, George Petekidis +1
Thixotropy is a phenomenon related to time dependent change in viscosity in presence or absence of flow. The yield stress, on the other hand, represents the minimum value of stress…
Dilatancy in dense suspensions of model hard-sphere-like colloids under shear and extensional flow
Ricardo J. E. Andrade, Alan R. Jacob, Francisco J. Galindo-Rosales +4
Dense suspensions of model hard-sphere-like colloids, with different particle sizes, are examined experimentally in the glass state, under shear and extensional rheology. Under ste…
Jamming Distance Dictates Colloidal Shear Thickening
Shravan Pradeep, Mohamad Nabizadeh, Alan R. Jacob +2
We report experimental and computational observations of dynamic contact networks for colloidal suspensions undergoing shear thickening. The dense suspensions are comprised of ster…
Colloidal Gels Tuned by Oscillatory Shear
E. Moghimi, A. R. Jacob, N. Koumakis +1
We examine microstructural and mechanical changes which occur during oscillatory shear flow and reformation after flow cessation of an intermediate volume fraction colloidal gel us…
Start-up Shear of Concentrated Colloidal Hard Spheres: Stresses, Dynamics and Structure
N. Koumakis, M. Laurati, A. R. Jacob +6
The transient response of model hard sphere glasses is examined during the application of steady rate start-up shear using Brownian Dynamics (BD) simulations, experimental rheology…
