  • Nucleation and arrest of dynamic slip on a pressurized fault 

    Garagash, Dmitry I., and Leonid N. Germanovich. 2012. "Nucleation and arrest of dynamic slip on a pressurized fault." Journal of Geophysical Research-Solid Earth 117: 10310-B10310. DOI:10.1029/2012JB009209
    Elevated pore pressure can lead to reactivation of slip on pre-existing fractures and faults when the static Coulomb failure is reached locally. As the pressurized region spreads diffusively, slip can accumulate quasi-statically ...
  • Plane-Strain Propagation of a Fluid-Driven Crack in a Permeable Rock with Fracture Toughness 

    Hu, J., and D. I. Garagash. 2010. "Plane-Strain Propagation of a Fluid-Driven Crack in a Permeable Rock with Fracture Toughness." Journal of Engineering Mechanics-Asce 136(9): 1152-1166.
    A solution to the problem of a plane-strain fluid-driven crack propagation in elastic permeable rock with resistance to fracture is presented. The fracture is driven by injection of an incompressible Newtonian fluid at a ...
  • Seismic and aseismic slip pulses driven by thermal pressurization of pore fluid 

    Garagash, D. I.. 2012. "Seismic and aseismic slip pulses driven by thermal pressurization of pore fluid." Journal of Geophysical Research-Solid Earth 117: 04314-B04314. DOI:10.1029/2011JB008889
    There are several lines of evidence that suggest that thermal pressurization (TP) of pore fluid within a low-permeability fault core may play the key role in the development of earthquake slip. To elucidate effects of TP ...
  • Multiscale tip asymptotics in hydraulic fracture with leak-off 

    Garagash, Dmitry I., Emmanuel Detournay, and Jose I. Adachi. 2011. "Multiscale tip asymptotics in hydraulic fracture with leak-off." Journal of Fluid Mechanics 669: 260-297.
    The authors studied the near-tip region of a fluid-driven fracture propagating in a permeable saturated rock. Fracturing of the rock and viscous flow in the fracture were taken into account, and leak-off and storage of the ...
  • Equilibrium of a pressurized plastic fluid in a wellbore crack 

    Garagash, D. I., and E. Sarvaramini. 2012. "Equilibrium of a pressurized plastic fluid in a wellbore crack." International Journal of Solids and Structures 49(1): 197-212.
