Tunable shear thickening in active frictional 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…
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…
Absorbing-state transitions in particulate systems under spatially varying driving
Bhanu Prasad Bhowmik, Christopher Ness
We study the absorbing state transition in particulate systems under spatially inhomogeneous driving using a modified random organization model. For smoothly varying driving the st…
Scaling description of frictionless dense suspensions under inhomogeneous flow
Bhanu Prasad Bhowmik, Christopher Ness
Predicting the rheology of dense suspensions under inhomogeneous flow is crucial in many industrial and geophysical applications, yet the conventional `' framework is limited…
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…
Creep failure of amorphous solids under tensile stress
Bhanu Prasad Bhowmik, H. G. E. Hentschel, Itamar Procaccia
Applying constant tensile stress to a piece of amorphous solid results in a slow extension, followed by an eventual rapid mechanical collapse. This "creep" process is of paramount…
Scaling Theory for Wöhler plots in amorphous solids under cyclic forcing
Bhanu Prasad Bhowmik, H. G. E. Hentschel, Itamar Procaccia
In mechanical engineering Wöhler plots serve to measure the average number of load cycles before materials break, as a function of the maximal stress in each cycle. Although such p…
Direct Measurement of Dipoles in Anomalous Elasticity of Amorphous Solids
Bhanu Prasad Bhowmik, Michael Moshe, Itamar Procaccia
Recent progress in studying the physics of amorphous solids has revealed that mechanical strains can be strongly screened by the formation of plastic events that are typically quad…
Soft-Pinning: Experimental Validation of Static Correlations in Supercooled Molecular Glass-forming Liquids
Rajsekhar Das, Bhanu Prasad Bhowmik, Anand B. Puthirath +2
Enormous enhancement in the viscosity of a liquid near its glass transition is generally connected to the growing many-body static correlations near the transition, often coined as…
Fatigue and Collapse of Cyclically Bent Strip of Amorphous Solid
Bhanu Prasad Bhowmik, H. G. E. Hentschel, Itamar Procaccia
Fatigue caused by cyclic bending of a piece of material, resulting in its mechanical failure, is a phenomenon that had been studied for ages by engineers and physicists alike. In t…
Thermodynamic Equivalence of Cyclic Shear and Deep Cooling in Glass-Formers
Bhanu Prasad Bhowmik, Valery Iylin, Itamar Procaccia
The extreme slowing down associated with glass formation in experiments and in simulations results in serious difficulties to prepare deeply quenched, well annealed, glassy materia…
Particle pinning suppresses spinodal criticality in the shear banding instability
Bhanu Prasad Bhowmik, Smarajit Karmakar, Itamar Procaccia +1
Strained amorphous solids often fail mechanically by creating a shear-band. It had been understood that the shear banding instability is usefully described as crossing a spinodal p…
