Electromagnetic actuator design for distributed stiffness
Origami robots characterized by rigid plates linked together with flexible joints have inherent compliance and large deformations. Their low-profile design and folding mechanical transmissions provide substantial force and torque, especially for wearables ...
IOP Publishing Ltd2022The Effects of Planetary and Stellar Parameters on Brittle Lithospheric Thickness
Marie Estelle Solange Violay, Michael Heap
The thicknesss of the brittle lithosphere—the outer portion of a planetary body that fails via fracturing— plays a key role in the geological processes of that body. The properties of both a planet and its host star can influence that thickness, and the po ...
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 ...
EPFL2021Geometrical control of fluid flow through single carbonate fracture
Fluid flow through single rough surface is critical for many geophysical processes and engineering applications. Thus, relations between flow and surrounding fracture geometry will be investigated. Four pairs of engineered Carrara marble surfaces with diff ...
2020Effects of composition and pressure on electronic states of iron in bridgmanite
Arnaud Magrez, Philippe Gillet, Susannah McGregor Dorfman
Electronic states of iron in the lower mantle's dominant mineral, (Mg,Fe,Al)(Fe,Al,Si)O-3 bridgmanite, control physical properties of the mantle including density, elasticity, and electrical and thermal conductivity. However, the determination of electroni ...
MINERALOGICAL SOC AMER2020How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach
Henri Joseph François Gilles Leclère
Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...
2019Mitigating tip vortex cavitation by a flexible trailing thread
Tip Vortex Cavitation (TVC) is a major issue in design and operation of axial hydraulic machines. We investigate the capacity of a flexible trailing thread in alleviating TVC by analyzing the flow-induced motion. For this purpose, a nylon thread with three ...
