Contact-network organization and motion statistics in shear-thickening suspensions
Michel Orsi, Rahul Pandare, Brolin Adu-Poku +2
We use lubricated-flow discrete-element-method (LF--DEM) simulations to examine how contact-network organization shapes particle motion in dense shear-thickening suspensions. The p…

Shear jamming and nonlinear rheology of chocolate suspensions
Michel Orsi, Veeraj Shah, Mahesh Padmanabhan +2
We experimentally investigate the rheology of dark chocolate pastes in both industrially relevant pre-refined form and simplified model systems. Steady and oscillatory shear experi…

Rigid clusters in shear-thickening suspensions: a nonequilibrium critical transition
Aritra Santra, Michel Orsi, Bulbul Chakraborty +1
The onset and growth of rigid clusters in a two-dimensional (2D) suspension in shear flow are studied by numerical simulations. The suspension exhibits the lubricated-to-frictional…
