Hydrodynamic dead zone in multiphase geophysical flows impacting a rigid obstacle

open access: yes, 2021
When a gravity-driven solid-fluid mixture, such as those in geophysical flows, hits a wall-like rigid obstacle, a metastable jammed zone called hydrodynamic dead zone (HDZ) may emerge.

Which effective viscosity? [PDF]

open access: yes, 2009
Magmas undergoing shear are prime examples of flows that involve the transport of solids and gases by a separate (silicate melt) carrier phase.

Experimental investigation on the rheology of fault rocks [PDF]

open access: yes, 2014
The aim of this study is to explore and identify physical and chemical processes occurring during deformation of fault rocks under elevated pressures and temperatures where an interplay between brittle/frictional and viscous processes is expected.

Fracture mechanics of volcanic eruptions [PDF]

open access: yes, 2009
Seismology is a key tool in the forecasting of volcanic eruptions. The onset of an eruption is often preceded and accompanied by an increase in local seismic activity, driven by fracturing within the edifice.

The Role of Shear Fabric in Controlling Breakdown Processes During Laboratory Slow‐Slip Events

open access: yes, 2020
Understanding the physical mechanisms at the origin of slow‐slip events has been proven a very challenging task. In particular, little is known on the role of fault heterogeneity during slow slip.

Locally Resolved Stress-State in Samples During Experimental Deformation: Insights Into the Effect of Stress on Mineral Reactions [PDF]

open access: yes, 2022
Understanding conditions in the Earth's interior requires data derived from laboratory experiments. Such experiments provide important insights into the conditions under which mineral reactions take place as well as processes that control the ...

An investigation on the mechanics of homogeneous expansion in gas-fluidized beds

open access: yes, 2015
The Richardson and Zaki (1954, Sedimentation and fluidization. Trans. Inst. Chem. Eng. 32, pp. 35–53.) equation has been used extensively to investigate the expansion profiles of homogeneous gas-fluidized beds.

Fluid Injection and the Mechanics of Frictional Stability of Shale-Bearing Faults [PDF]

open access: yes, 2018
Fluid overpressure is one of the primary mechanisms for triggering tectonic fault slip and human-induced seismicity. This mechanism is appealing because fluid overpressure reduces the effective normal stress, hence favoring fault reactivation. However,

Booming Sand Dunes [PDF]

open access: yes, 2010
"Booming" sand dunes are able to produce low-frequency sound that resembles a pure note from a music instrument. The sound has a dominant audible frequency (70-105 Hz) and several higher harmonics and may be heard from far distances away.

The mechanics of lubricated faults: Insights from 3-D numerical models

open access: yes, 2012
The weakening mechanisms occurring during an earthquake failure are of prominent importance in determining the resulting energy release and the seismic waves excitation.
