The failure behavior of geological materials depends heavily on confining pressure and
strain rate. Under a relatively low confining pressure, these materials tend to fail by brittle …

Nanoindentation tests, spanning various length scales ranging from 200 nm to 5 μm deep,
were performed on a sample of organic-rich Woodford shale in both the bedding plane …

Geologic shear fractures such as faults and slip surfaces involve marked friction along the
discontinuities as they are subjected to significant confining pressures. This friction plays a …

We introduce a phase‐field method for continuous modeling of cracks with frictional
contacts. Compared with standard discrete methods for frictional contacts, the phase‐field …

Understanding geomechanical properties of shales, such as stiffness properties and fracture
toughness, is important in different areas of petroleum industry-related activities. Nanoscale …

We present a barrier method for treating frictional contact on interfaces embedded in finite
elements. The barrier treatment has several attractive features, including:(i) it does not …

We utilize smoothed particle hydrodynamics (SPH), a Lagrangian particle-based continuum
method, to study the initiation and propagation of shear bands or faults in geologic materials …

This article presents a fully coupled finite element method for the single cohesive fracture
propagation in a deformable porous medium (rock) interacting with two immiscible pore …

In this study we introduce and utilize GEOSPH, a Lagrangian particle-based continuum
Smoothed Particle Hydrodynamics (SPH) code to simulate the deformation of geologic …

Earthquake ruptures in poroelastic media involve a suite of complex phenomena arising
from stick‐slip frictional instabilities and thermo‐hydromechanical couplings. In this study we …
