Attention network forecasts time-to-failure in laboratory shear experiments

Hope Jasperson, David C. Bolton, Paul Johnson +3

Rocks under stress deform by creep mechanisms that include formation and slip on small-scale internal cracks. Intragranular cracks and slip along grain contacts release energy as e…

Plate motion in sheared granular fault system

Ke Gao, Robert A. Guyer, Esteban Rougier +1

Plate motion near the fault gouge layer, and the elastic interplay between the gouge layer and the plate under stick-slip conditions, is key to understanding the dynamics of sheare…

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…

From Stress Chains to Acoustic Emission

Ke Gao, Robert Guyer, Esteban Rougier +2

A numerical scheme using the combined finite-discrete element methods (FDEM) is employed to study a model of an earthquake system comprising a granular layer embedded in a formatio…

Simulation of crack induced nonlinear elasticity using the combined finite-discrete element method

Ke Gao, Esteban Rougier, Robert Guyer +2

Numerical simulation of nonlinear elastic wave propagation in solids with cracks is indispensable for decoding the complicated mechanisms associated with the nonlinear ultrasonic t…

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…
