Tunable shear thickening in active non-Brownian suspensions
Bhanu Prasad Bhowmik, Christopher Ness
We study tunable shear thickening in active suspensions of non-Brownian, repulsive, frictional grains using particle-based simulation, finding that activity augments the rheology b…
Finite Disorder Critical Point in Brittle-to-Ductile Transition in Amorphous Solids with Aspherical Impurities
Anoop Mutneja, Bhanu Prasad Bhowmik, Smarajit Karmakar
Enhancing the mechanical properties of amorphous solids is crucial for material design, with microalloying being a common but not well-understood method. Using extensive molecular…
Tuning the Viscosity and Jamming Point in Dense Active non-Brownian Suspensions
Bhanu Prasad Bhowmik
Using numerical simulations, we study the rheological response of dense non-Brownian suspensions containing active particles. The active particles are modelled as run-and-tumble pa…
Finite Disorder Critical Point in the Brittle-to-Ductile Transition of Amorphous Solids in the Presence of Particle Pinning
Anoop Mutneja, Bhanu Prasad Bhowmik, Smarajit Karmakar
The mechanical yielding of amorphous solids under external loading can be broadly classified into ductile and brittle types, depending on whether their macroscopic stress response…
Unifying homogeneous and inhomogeneous rheology of dense suspensions
Bhanu Prasad Bhowmik, Christopher Ness
The rheology of dense suspensions lacks a universal description due to the involvement of a wide variety of parameters, ranging from the physical properties of solid particles to t…
