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 …

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 …

A thermodynamically consistent phase field model with new crack driving forces is proposed
to simulate the mixed-mode fracture phenomena in rock-like materials. The governing …

We present a new phase-field formulation for the formation and propagation of a compaction
band in high-porosity rocks. Novel features of the proposed formulation include (a) the …

This paper presents new finite elements that incorporate strong discontinuities with linear
interpolations of the displacement jumps for the modeling of failure in solids. The cases of …

This paper has two objectives:(a) to formulate a mechanical theory of porous continua within
the framework of strong discontinuity concept commonly employed for the analysis of strain …

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 …

This paper presents a finite element model for strain localization analysis of elastoplastic
solids subjected to discontinuous displacement fields based on standard Galerkin …

We present an incremental quasi‐static contact algorithm for path‐dependent frictional crack
propagation in the framework of the extended finite element (FE) method. The discrete …

Compaction bands are tabular regions of localized compressive deformation with little or no
shear offset. Often observed in high‐porosity rocks, they can be classified into several …
