One of the first courses I taught at Stanford was Advanced Soil Mechanics. The course title
was accurate in the beginning, but the contents gradually became more and more about …

Mechanically-based numerical modeling is a powerful tool for investigating fundamental
processes associated with the formation and evolution of both large and small-scale …

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 present the first mixed mode phase-field model of ductile fracture. The contribution of
crack opening and shearing deformations to the propagation of a crack is expressed by …

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 …

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 …

Abstract Cracks, veins, joints, faults, and ocean crusts are strong discontinuities of different
length scales that can be found in many geological formations. While the constitutive laws …
