Disentangling microstructural elements of shear thickening suspensions via computer simulations of a minimal model
William C. J. Buchholtz, Daniel L. Blair, Jeffrey S. Urbach +2
We use a minimal model for a dense suspension undergoing thickening and thinning to investigate microstructural changes in 2d simulations. Our simulations show that in steady flow…
Pinch-point Singularities in Stress-Stress Correlations Reveal Rigidity in Colloidal Gels
Albert Countryman, H. A. Vinutha, Fabiola Diaz Ruiz +3
We demonstrate that the spatial correlations of microscopic stresses in 2D model colloidal gels obtained in computer simulations can be quantitatively described by the predictions…
Memory of shear flow in soft jammed materials
H. A. Vinutha, Manon Marchand, Marco Caggioni +3
Cessation of flow in simple yield stress fluids results in a complex stress relaxation process that depends on the preceding flow conditions and leads to finite residual stresses.…
Discontinuous rigidity transition associated with shear jamming in granular simulations
Varghese Babu, H. A Vinutha, Dapeng Bi +1
We investigate the rigidity transition associated with shear jamming in frictionless, as well as frictional, disk packings in the quasi-static regime and at low shear rates. For fr…
Stress-stress Correlations Reveal Force Chains in Gels
H. A. Vinutha, Fabiola Diaz Ruiz, Xiaoming Mao +2
We investigate the spatial correlations of microscopic stresses in soft particulate gels, using 2D and 3D numerical simulations. We use a recently developed theoretical framework p…
Estimation of the equilibrium free energy for glasses using the Jarzynski equality
H. A. Vinutha, Daan Frenkel
The free energy of glasses cannot be estimated using thermodynamic integration, as glasses are intrinsically not in equilibrium. We present numerical simulations showing that, in c…
