Orthogonal Superposition Rheometry of soft core-shell microgels
Panagiota Bogri, Gabriele Pagani, Jan Vermant +2
The mechanisms of flow in suspensions of soft particles above the glass-transition volume fraction and in the jammed state were probed using Orthogonal Superposition Rheometry (OSR…
High-frequency Optimally Windowed Chirp rheometry for rapidly evolving viscoelastic materials: application to a crosslinking thermoset
Thanasis Athanasiou, Michela Geri, Patrice Roose +2
Abstract Knowledge of the evolution of mechanical properties of the curing matrix is of great importance in composite parts or structure fabrication. Conventional rheometry, based…
Yielding under the microscope: a multi-scale perspective on brittle and ductile behaviors in oscillatory shear
P. Edera, M. Brizioli, M. Madani +6
We study the yielding transition in soft jammed materials under oscillatory shear, employing a novel methodology that combines rheological measurements with detailed dynamical obse…
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…
Shear induced tuning and memory effects in colloidal gels of rods and spheres
Mohan Das, George Petekidis
Shear history plays an important role in determining the linear and nonlinear rheological response of colloidal gels and can be used for tuning their structure and flow properties.…
Tuning local microstructure of colloidal gels by ultrasound-activated deformable inclusions
Brice Saint-Michel, George Petekidis, Valeria Garbin
Colloidal gels possess a memory of previous shear events, both steady and oscillatory. This memory, embedded in the microstructure, affects the mechanical response of the gel, and…
