Fluid-saturated granular and porous layers can undergo liquefaction and lose their shear resistance when subjected to shear forcing. In geosystems, such a process can lead to severe natural hazards of soil liquefaction, accelerating slope failure, and large earthquakes. Terzaghi's principle of effective stress predicts that liquefaction occurs when the pore pressure within the layer becomes equal to the applied normal stress on the layer. However, under dynamic loading and when the internal…

Compaction front and pore fluid pressurization in horizontally shaken drained granular layers

We numerically simulate a gently shaken fluid-saturated granular layer. Above a critical imposed acceleration an upward moving compaction front forms. The front divides the layer in two: above the

Bridging aero-fracture evolution with the characteristics of the acoustic emissions in a porous medium

The characterization and understanding of rock deformation processes due to fluid flow is a challenging problem with numerous applications. The signature of this problem can be found in Earth Science

How Stress and Temperature Conditions Affect Rock-Fluid Chemistry and Mechanical Deformation

We report the results from a series of chalk flow-through-compaction experiments performed at three effective stresses (0.5 MPa, 3.5 MPa and 12.3 MPa) and two temperatures (92℃ and and 130℃). The

The Mechanical Coupling of Fluid-Filled Granular Material Under Shear

The coupled mechanics of fluid-filled granular media controls the physics of many Earth systems, for example saturated soils, fault gouge, and landslide shear zones. It is well established that when

A simple model for granular flows with hydrodynamic interactions that relies on a coarse grained picture of the granular medium, and is described in terms of the pressure by a local Darcy law to avoid the large computational cost of solving for detailed hydrod dynamic flow fields between grains.

The effect of an interstitial fluid on the mixing of sedimenting grains is studied numerically in a closed rectangular Hele-Shaw cell and the emerging patterns do not seem highly affected by the compressibility change studied.
