The effect of particle shape on discharge and clogging. [PDF]
Sci Rep, 2021 Granular flow is common across different fields from energy resource recovery and mineral processing to grain transport and traffic flow. Migrating particles may jam and form arches that span constrictions and hinder particle flow.

Transforming mesoscale granular plasticity through particle shape [PDF]
Physical Review X, 2018 When an amorphous material is strained beyond the point of yielding it enters a state of continual reconfiguration via dissipative, avalanche-like slip events that relieve built-up local stress.

Thermo-responsive jamming by particle shape change [PDF]
Nature CommunicationsGranular materials transition between unjammed (deformable) and jammed (rigid) states when adjusting their packing density. Here, we report on experiments demonstrating that the same kind of phase transition can be alternatively achieved through ...

The Effect of Particle Shape on the Compaction of Realistic Non-Spherical Particles—A Multi-Contact DEM Study [PDF]
Pharmaceutics, 2023 The purpose of this study was to investigate the deformation behavior of non-spherical particles during high-load compaction using the multi-contact discrete element method (MC-DEM). To account for non-spherical particles, the bonded multi-sphere method (

Effect of particle shape on particle breakage inside rotating cylinders [PDF]
EPJ Web of Conferences, 2021 We study the influence of particle shape on the evolution of particle breakage process taking place inside rotating cylinders. Extensive particle dynamics simulations taking into account the dynamics of the granular flow, particle breakage, and polygonal
