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 …

Contact problem suffers from a numerical instability similar to that encountered in
incompressible elasticity, in which the normal contact pressure exhibits spurious oscillation …

During the operation of tunnels, a problem that is encountered often is the cracking of
secondary lining caused by the time-dependent deformation of weak surrounding rocks. In …

In this paper, an Uzawa-type augmented Lagrangian contact formulation is presented for
modeling frictional discontinuities in the framework of the X-FEM technique. The …

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 investigate a finite element method for frictional sliding along embedded interfaces
within a weighted Nitsche framework. For such problems, the proposed Nitsche stabilized …

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 …

We present an extended finite element framework to numerically study competing hydraulic
fracture propagation. The framework is capable of modeling fully coupled hydraulic …

The assumed enhanced strain (AES) method is developed to simulate cohesive fracture
propagation in the partially saturated porous media which includes the solid skeleton and …
