Bonded-particle model for magneto-elastic rods
Gabriel Alkuino, Joel T. Clemmer, Christian D. Santangelo +1
We develop a bonded-particle model for magneto-elastic rods that unifies large deformations, contact, and long-range magnetic interactions within a single discrete-element framewor…
Shear and crystallization in deformable granular packings: why don't auxetics order?
Joel T. Clemmer, Nicholas W. Hackney, Gary S. Grest
Shear of three-dimensional, highly compressed granular packings is simulated using a bonded particle approach that explicitly resolves elastic deformation. Varying Poisson's ratio…
Reverse segregation and self-organization in inclined chute flows of bidisperse granular mixtures
Joseph M. Monti, Joel T. Clemmer, Ishan Srivastava +3
In the usual segregation scenario for stable inclined chute flows of bidisperse mixtures of fine and coarse spherical particles, coarse particles rise toward the free surface, form…
Shape Elasticity in Colloidal Bent-Core Liquid Crystals
Nicholas W. Hackney, Joel T. Clemmer, Gary S. Grest
Curved particles have been shown to stabilize a range of states with unique order in dense suspensions of colloidal bent core liquid crystals. The shape of the colloidal rods encou…
Emergence of Intermediate Range Order in Jammed Packings
Joseph M. Monti, Ishan Srivastava, Leonardo E. Silbert +3
We perform a structural analysis of large scale jammed packings of monodisperse, frictionless and frictional spheres to elucidate structural signatures of the static structure fact…
Onset and impact of plastic deformation in granular compaction
Joel T. Clemmer, Jeremy B. Lechman
The role of plastic deformation in the high-pressure compaction of granular material is investigated using bonded particle model simulations. Grains are discretized into a set of c…
