A Scalable OpenLB LAMMPS Framework for Fully Resolved Simulations of Hindered Settling of Arbitrary Non-Spherical Particles
Varghese Babu, Adrian Kummerländer, Mathias J. Krause +2
Hindered settling of non spherical particles remains significantly less understood than spherical particles due to the computational challenges in resolving the complex contact mec…
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…
Criticality and marginal stability of the shear jamming transition of frictionless soft spheres
Varghese Babu, Srikanth Sastry
We study numerically the critical behavior and marginal stability of the shear jamming transition for frictionless soft spheres, observed to occur over a finite range of densities,…
Is friction essential for dilatancy and shear jamming in granular matter?
Varghese Babu, Deng Pan, Yuliang Jin +2
Granular packings display the remarkable phenomenon of dilatancy [1], wherein their volume increases upon shear deformation. Conventional wisdom and previous results suggest that d…
