Frictional weakening leads to unconventional singularities during dynamic rupture propagation
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, François Xavier Thibault Passelègue, Federica Paglialunga
Earthquakes i.e. frictional ruptures, are commonly described by singular solutions of shear crack motions. These solutions assume a square root singularity order around the rupture tip and a constant shear stress value behind it, implying scale-independent ...
2024Proliferation-driven mechanical compression induces signalling centre formation during mammalian organ development
Localized sources of morphogens, called signalling centres, play a fundamental role in coordinating tissue growth and cell fate specification during organogenesis. However, how these signalling centres are established in tissues during embryonic developmen ...
Nature Portfolio2024Single-Well Pore Pressure Preconditioning for Enhanced Geothermal System Stimulation
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, Barnaby Padraig Fryer
The stress state is an important parameter in terms of both earthquake nucleation and rupture. Here, a new stimulation technique is proposed for Enhanced Geothermal Systems (EGSs), which have previously been burdened with a number of high-profile incidence ...
AMER GEOPHYSICAL UNION2023Shear strength and shear stiffness analysis of compacted Wyoming-type bentonite
Wyoming-type bentonite is one of the materials to be used as part of the Engineered Barrier System (EBS) in deep geological disposal facilities for the safe disposal of spent nuclear fuel.In the KBS-3 type repository, the canisters containing the spent fue ...
ELSEVIER2023Bounding the localized to ductile transition in porous rocks: implications for geo-reservoirs
Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer
Porous rocks have long been the focus of intense research driven by their importance in our society as host to our most essential resources (oil, gas, water, geothermal energy, etc), yet their rheology remains poorly understood. With increasing depth, poro ...
2023Drained Clay-Pipe Interface Resistance at Low Normal Stresses and Elevated Temperatures
Offshore pipelines that transport hydrocarbons under high pressure and high temperature are usually thermally insulated to maintain an elevated temperature and prevent any heat loss to the surroundings. However, the temperatures at the outer-wall of the pi ...
AMER SOC CIVIL ENGINEERS2023Influence of Viscous Lubricant on Nucleation and Propagation of Frictional Ruptures
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Federica Paglialunga
Fluids are pervasive in the Earth's crust and saturate fractures and faults. The combination of fluids and gouge layers developing along faults can generate fluids of different viscosities. Such viscous fluids were found to influence the reactivation, fric ...
AMER GEOPHYSICAL UNION2023Study of backward Brillouin scattering in gas-filled anti-resonant fibers
Luc Thévenaz, Malak Mohamed Hossameldeen Omar Mohamed Galal, Li Zhang
Brillouin scattering in gas shows unmatched gain properties in hollow-core optical fibers filled at high pressure. Here, the gain characteristics are studied for two common gases, namely, N2 and CO2, which show distinct features and are compared to expecte ...
2023Fault roughness’s influence on experimental fault mechanical behavior
Brice Tanguy Alphonse Lecampion, Marie Estelle Solange Violay, Barnaby Padraig Fryer, Seyyedmaalek Momeni, François Xavier Thibault Passelègue, Carolina Giorgetti
Fault slip behavior and earthquake nucleation are often framed within the context of velocity-dependent friction, ranging from velocity-strengthening to velocity-weakening behavior. Previous studies have shown that fault roughness controls the fault slip b ...
2022Determination of Parameters Characteristic of Dynamic Weakening Mechanisms During Seismic Faulting in Cohesive Rocks
Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Chiara Cornelio
While sliding at seismic slip-rates of ∼1 m/s, natural faults undergo an abrupt decrease of shear stress called dynamic weakening. Asperity-scale processes related to flash heating and weakening and, meso-scale (mm-cm) processes involving shear across the ...
