Coupling Heterarchical Granular Dynamics and Computational Fluid Dynamics
Jiahuan Li, Shivakumar Athani, Alistair Gillespie +3
Granular flows in ambient fluids exhibit grain-size-dependent segregation, which is difficult to capture efficiently with existing models, especially in large-scale systems involvi…
The influence of grain crushing and pore collapse on the formation of faults
N. A. Collins-Craft, I. Stefanou, J. Sulem +1
During an earthquake, slip occurs in a localised shear zone that features a heavily granulated fault core that can be characterised as a shear band. We study the formation of this…
Scale dependence of segregation patterns in the filling of silos
Shivakumar Athani, Benjy Marks, François Guillard +2
Size segregation in granular flows is a well-known phenomenon: laboratory experiments consistently show that large particles migrate toward silo walls during filling, while smaller…
Heterarchical Granular Dynamics
Benjy Marks, Shivakumar Athani, Itai Einav
The two most commonly used methods to model the behaviour of granular flows are discrete element and continuum mechanics simulations. These approaches concentrate on the determinis…
Hydrodynamics of fault gouges from constitutive modelling to the physics of friction
Filippo Masi, Itai Einav
The development of rate- and state-dependent friction laws offered important insights into the key physical mechanisms of the frictional behaviour of fault gouges and their seismic…
Neural integration for constitutive equations using small data
Filippo Masi, Itai Einav
Data-driven models based on deep learning algorithms intend to overcome the limitations of traditional constitutive modelling by directly learning from data. However, the need for…
