A semi-infinite hydraulic fracture propagating in a poroelastic medium
Evgenii Kanin, Andreas Möri, Dmitry Garagash +1
We solve the near-tip coupled hydromechanical problem of a hydraulic fracture propagating in a permeable poroelastic medium, represented locally as a semi-infinite crack moving at…
Steadily moving semi-infinite fracture in plane poroelasticity
Evgenii Kanin, Andreas Möri, Dmitry Garagash +1
We present a boundary integral formulation for steadily propagating semi-infinite plane strain tensile and shear fractures in poroelastic media. By combining fundamental solutions…
Linear and nonlinear stability of rate-and-state faults
Robert C. Viesca, Dmitry I. Garagash
Models of faults incorporating slip rate- and state-dependent friction have reproduced phenomena from spontaneous slow, aseismic slip to earthquake-generating dynamic rupture. Nume…
Propagation of Elongated Fluid-Driven Fractures: Rock Toughness vs. Fluid Viscosity
Dmitry I. Garagash
This paper studies the effect of the rock fracture toughness on the propagation of elongated fluid-driven fractures. We use the `tough PKN' model of Sarvaramini and Garagash (2015)…
Ground Motion Characteristics of Cascading Earthquakes in a Multiscale Fracture Network
Kadek Hendrawan Palgunadi, Alice-Agnes Gabriel, Dmitry Igor Garagash +3
Fault zones exhibit geometrical complexity and are often surrounded by multiscale fracture networks within their damage zones, influencing rupture dynamics and near-field ground mo…
Fault-size dependent fracture energy explains multi-scale seismicity and cascading earthquakes
Alice-Agnes Gabriel, Dmitry I. Garagash, Kadek H. Palgunadi +1
Earthquakes vary in size over many orders of magnitude, yet the scaling of the earthquake energy budget remains enigmatic. We propose that fundamentally different "small-slip" and…
Rupture Dynamics of Cascading Earthquakes in a Multiscale Fracture Network
Kadek Hendrawan Palgunadi, Alice-Agnes Gabriel, Dmitry Igor Garagash +2
Fault-damage zones comprise multiscale fracture networks that may slip dynamically and interact with the main fault during earthquake rupture. Using 3D dynamic rupture simulations…
CO2 storage in deep saline aquifers: evaluation of geomechanical risks using integrated modeling workflow
Evgenii Kanin, Igor Garagash, Sergei Boronin +5
CO2 injection into a saline aquifer crossed by a tectonic fault is studied with coupled fluid mechanics - geomechanics modeling. The simulation approach is based on coupling of the…
Notes on Hydraulic Fracture Mechanics
Dmitry I. Garagash
These notes address the mechanics of propagating hydraulic fractures (HF). In the first part, we focus on how different physical mechanisms (dissipation in fluid and solid, fluid s…
Notes on Propagation of 3D Buoyant Fluid-Driven Cracks
Dmitry I. Garagash, Leonid N. Germanovich
Magma-driven fractures are the main mechanism for magma emplacement in the crust. A fundamental question is how the released fluid controls the propagation dynamics and fracture ge…
Stability of pulse-like earthquake ruptures
Nicolas Brantut, Dmitry I. Garagash, Hiroyuki Noda
Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating und…
Confined flow of suspensions modeled by a frictional rheology
Brice Lecampion, Dmitry I. Garagash
We investigate in detail the problem of confined pressure-driven laminar flow of neutrally buoyant non-Brownian suspensions using a frictional rheology based on the recent proposal…
