Dynamics, radiation and overall energy budget of earthquake rupture with coseismic off-fault damage
Kurama Okubo, Harsha S. Bhat, Esteban Rougier +5
Earthquake ruptures dynamically activate coseismic off-fault damage around fault cores. Systematic field observation efforts have shown the distribution of off-fault damage around…
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…
Simulation of fracture coalescence in granite via the combined finite-discrete element method
Bryan Euser, Esteban Rougier, Zhou Lei +5
Fracture coalescence is a critical phenomenon for creating large fractures from smaller flaws, affecting fracture network flow and seismic energy release potential. In this paper,…
A generalized anisotropic deformation formulation for geomaterials
Zhou Lei, Esteban Rougier, Earl E. Knight +2
In this paper, the Combined Finite-Discrete Element Method (FDEM) has been applied to analyze the deformation of anisotropic geomaterials. In the most general case geomaterials are…
Earthquake damage patterns resolve complex rupture processes
Yann Klinger, Kurama Okubo, Amaury Vallage +9
Large continental earthquakes activate multiple faults in a complex fault system, dynamically inducing co-seismic damage around them. The 2016 Mw 7.8 Kaikoura earthquake in the nor…
