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.…
Timescale divergence at the shear jamming transition
H. A. Vinutha, Kabir Ramola, Bulbul Chakraborty +1
We find that in simulations of quasi-statically sheared frictional disks, the shear jamming transition can be characterized by an abrupt jump in the number of force bearing contact…
The jamming transition is a k-core percolation transition
Flaviano Morone, Kate Burleson-Lesser, H. A. Vinutha +2
We explain the structural origin of the jamming transition in jammed matter as the sudden appearance of k-cores at precise coordination numbers which are related not to the isostat…
