Boundary and mixed lubrication are usually used to reduce friction in sheet metal form- ing. In the boundary lubrication regime load is mainly carried by contacting asperities. Therefore, the tribological problem can be solved in the dry case using a geome ...
2023Spatio-temporal patterns of fluid-driven aseismic slip transients: implications to seismic swarms
Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe
Seismic swarms are often interpreted to be driven by natural fluid pressurization in the Earth’s crust, when seismicity is observed to spread away from a common origin and follows approximately a square-root-of-time pattern of growth. On the other hand, a ...
EGU2022Friction Induces Anisotropic Propulsion in Sliding Magnetic Microtriangles
In viscous fluids, motile microentities such as bacteria or artificial swimmers often display different transport modes than macroscopic ones. A current challenge in the field aims at using friction asymmetry to steer the motion of microscopic particles. H ...
AMER CHEMICAL SOC2022Frictional behaviour of carbonate bearing faults at brittle-ductile transition
Marie Estelle Solange Violay, Mathias Alexandre David Lebihain, Carolina Giorgetti, Francesco Figura
One of the most alarming recent findings in geo-science is the dramatic rise in the rate of humaninduced earthquakes in the past decade. This is due to the fluid injection or extraction in deep reservoirs for hydrocarbon production, wastewater and CO2 stor ...
2021On the effects of fluid pressure variations on rock-mass and fault mechanical behaviour
In the past 20 years, the growing interest in deep geo-reservoirs for purposes such as carbon storage, waste water disposal, or geothermal energy exploitation have led to large-volume fluid injections into the upper continental crust. These fluid injection ...
EPFL2021The Role of Geometrical Parameters in the Lubrication of the Swiss Lever Escapement
The lubrication regimes of a contact pair escapement-ruby pallet of a Swiss lever escapement have been investigated combining the theory of fluid lubrication with a well-established kinematic and inverse dynamic multibody model. The kinematic analytical re ...
2021Three-dimensional fluid-driven stable frictional ruptures
Brice Tanguy Alphonse Lecampion, Alexis Alejandro Sáez Uribe
We investigate the quasi-static growth of a fluid-driven frictional shear crack that propagates in mixed mode (II+III) on a planar fault interface that separates two identical half-spaces of a three-dimensional solid. The fault interface is characterized b ...
2021BEM Study of the Contact between Rough Surfaces for Dry and Lubricated Condition
Friction is one of the most important topics in contact mechanics and the real contact area plays a significant role in determining the emergent friction properties. We study the detachment of the original contact clusters during the surface sliding. The e ...
