Solutions for thermally mismatched brazing operations for ceramic tokamak magnetic sensor

Duccio Testa, Peter Ryser, Matthieu Toussaint, Thomas Maeder, Caroline Jacq, Philipp Windischhofer, Xinyue Jiang

To monitor high-frequency fluctuations of the equilibrium magnetic field in tokamaks, a 3D magnetic sensor has been developed. The sensor, which is positioned inside the vacuum vessel behind the protective tiles of the tokamak and is exposed to potential t ...

Scaling in natural and laboratory earthquakes

Marie Estelle Solange Violay

Laboratory experiments reproducing seismic slip conditions show extreme frictional weakening due to the activation of lubrication processes. Due to a substantial variability in the details of the weakening transient, generalization of experimental results ...

The dynamics of a capsule in a wall-bounded oscillating shear flow

Lailai Zhu

The motion of an initially spherical capsule in a wall-bounded oscillating shear flow is investigated via an accelerated boundary integral implementation. The neo-Hookean model is used as the constitutive law of the capsule membrane. The maximum wall-norma ...

Optimisation of industrial production of low-force sensors – adhesive bonding of force-centring ball

Peter Ryser, Thomas Maeder, Caroline Jacq, Maxime Blot

This work addresses the issue of attaching the force-centring part (a round ball) to the load cell of a force sensor, a piezoresistive thick-film Wheatstone bridge deposited onto a ceramic cantilever. As the current soldering process requires expensive met ...

Experimental investigation and modelling of the structural behaviour of confined grouted interfaces for a new steel–concrete connection

Jean-Paul Lebet, Dimitrios Papastergiou

Confined interfaces between cement grout and other materials such as embossed steel or rough concrete are formed in an innovative new steel-concrete connection for composite bridges. This article presents the experimental study of such interfaces and inves ...

The experimental study introduces an unload-induced direct-shear model to investigate the frictional slip of a layer of simulated granular gouges induced by the combination of a decreasing normal stress and a constant shear stress. A frictional equilibrium ...

American Institute of Physics2014

This study presents a dynamic-induced direct-shear model to investigate the dynamic triggering of frictional slip on simulated granular gouges. An incident P-wave is generated as a shear load and a normal stress is constantly applied on the gouge layer. Th ...

Avalanche of fluid in the laboratory: the dam-break problem revisited.

Christophe Ancey

The talk reviews some of the analytical results available for studying the dambreak problem. Emphasis is then given to a thorough comparison between experimental data, analytical results (lubrication theory), and numerical simulations (obtained using the s ...
