Critical transitions on route to chaos of natural convection on a heated horizontal circular surface
Yuhan Jiang, Yongling Zhao, Jan Carmeliet +2
The transition route and bifurcations of the buoyant flow developing on a heated circular horizontal surface are elaborated using direct numerical simulations and direct stability…
Betweenness centrality illuminates intermittent frictional dynamics
Omid Dorostkar, Karen E. Daniels, Dominik Strebel +1
Dense granular systems subjected to an imposed shear stress undergo stick-slip dynamics with systematic patterns of dilation-compaction. During each stick phase, as the frictional…
Machine Learning Reveals the State of Intermittent Frictional Dynamics in a Sheared Granular Fault
C. X. Ren, O. Dorostkar, B. Rouet-Leduc +5
Seismogenic plate boundaries are presumed to behave in a similar manner to a densely packed granular medium, where fault and blocks systems rapidly rearrange the distribution of fo…
Modeling of Stick-Slip Behavior in Sheared Granular Fault Gouge Using the Combined Finite-Discrete Element Method
Ke Gao, Bryan J. Euser, Esteban Rougier +5
Sheared granular layers undergoing stick slip behavior are broadly employed to study the physics and dynamics of earthquakes. Here, a two dimensional implementation of the combined…
Dynamic induced softening in frictional granular material investigated by DEM simulation
Laure Lemrich, Paul A. Johnson, Robert Guyer +2
A granular system composed of frictional glass beads is simulated using the Discrete Element Method. The inter-grain forces are based on the Hertz contact law in the normal directi…
Acoustically-induced slip in sheared granular layers: application to dynamic earthquake triggering
Behrooz Ferdowsi, Michele Griffa, Robert A. Guyer +3
A fundamental mystery in earthquake physics is ``how can an earthquake be triggered by distant seismic sources?'' Here, we use discrete element method simulations of a granular lay…
Effect of boundary vibration on the frictional behavior of a dense sheared granular layer
B. Ferdowsi, M. Griffa, R. A. Guyer +2
We report results of 3D Discrete Element Method (DEM) simulations aiming at investigating the role of the boundary vibration in inducing frictional weakening in sheared granular la…
