Merons Mediate Re-Ordering of Curved Rods Under Shear Flow
Nicholas W. Hackney, Joel T. Clemmer, Thomas O'Connor +1
Bent-core liquid crystals are a canonical example of a soft matter system whose behavior is controlled by a local preference for order that cannot be universally achieved. This geo…
A soft departure from jamming: the compaction of deformable granular matter under high pressures
Joel T. Clemmer, Joseph M. Monti, Jeremy B. Lechman
The high-pressure compaction of three dimensional granular packings is simulated using a bonded particle model (BPM) to capture linear elastic deformation. In the model, grains are…
Universal behavior in fragmenting brittle, isotropic solids across material properties
Joel T. Clemmer, Mark O. Robbins
A bonded particle model is used to explore how variations in the material properties of brittle, isotropic solids affect critical behavior in fragmentation. To control material pro…
Large-scale frictionless jamming with power-law particle size distributions
Joseph M. Monti, Joel T. Clemmer, Ishan Srivastava +3
Due to significant computational expense, discrete element method simulations of jammed packings of size-dispersed spheres with size ratios greater than 1:10 have remained elusive,…
Shear Is Not Always Simple: Rate-Dependent Effects of Flow Type on Granular Rheology
Joel T. Clemmer, Ishan Srivastava, Gary S. Grest +1
Despite there being an infinite variety of types of flow, most rheological studies focus on a single type such as simple shear. Using discrete element simulations, we explore bulk…
Jamming of Bidisperse Frictional Spheres
Ishan Srivastava, Scott A. Roberts, Joel T. Clemmer +3
By generalizing a geometric argument for frictionless spheres, a model is proposed for the jamming density of mechanically stable packings of bidisperse, frictional spheres.…
Criticality in sheared, disordered solids. II. Correlations in avalanche dynamics
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Disordered solids respond to quasistatic shear with intermittent avalanches of plastic activity, an example of the crackling noise observed in many nonequilibrium critical systems.…
Criticality in sheared, disordered solids. I. Rate effects in stress and diffusion
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Rate-effects in sheared disordered solids are studied using molecular dynamics simulations of binary Lennard-Jones glasses in two and three dimensions. In the quasistatic (QS) regi…
Anisotropic Avalanches and Critical Depinning of Three-Dimensional Magnetic Domain Walls
Joel T. Clemmer, Mark O. Robbins
Simulations with more than spins are used to study the motion of a domain wall driven through a three-dimensional random-field Ising magnet (RFIM) by an external field $H…
