Cell-based Automatic Deformation Computation by Analyzing Terrestrial LIDAR Point Clouds

Pierre-Yves Gilliéron, Bertrand Merminod, Jing Wu

This paper presents a cell-based approach for computing the deformation of a monitored object by analyzing point cloud data from terrestrial lidar. This approach can automatically generate an informative deformation description (called "deformation map") w ...

Simulation of the welding process of steel tube joints made of S355 and S690

Janna Krummenacker

Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...

Hydro-mechanical coupling in the periodontal ligament: A porohyperelastic finite element model

Matteo Galli, Joël Cugnoni, Marzio Bergomi

Harmonic tension–compression tests at 0.1, 0.5 and 1 Hz on hydrated bovine periodontal ligament (PDL) were numerically simulated. The process was modeled by finite elements (FE) within the framework of poromechanics, with the objective of isolating the con ...

Ultra-low pressure sensor for neonatal resuscitator

Peter Ryser, Thomas Maeder, Caroline Jacq, Nicolas Craquelin, Enrico Haemmerle

In this work, we study in detail the sensing characteristics of piezoresistive force sensors based on structured LTCC (Low Temperature Co-fired Ceramic) cantilevers carrying a thick-film piezoresistive bridge. These devices show much improved sensitivity c ...

Highly filled polymer nanocomposite films derived from novel nanostructured latexes

Riccardo Ruggerone

The overall aim of this thesis has been to assess the potential of latex-based technologies for the preparation of polymer/clay nanocomposites. The key feature of latex-based technologies is that they offer the possibility of improved control of the final ...

A multi-scale approach for high cycle anisotropic fatigue resistance: Application to forged components

Roland Logé

Forged components exhibit good mechanical strength, particularly in terms of high cycle fatigue properties. This is due to the specific microstructure resulting from large plastic deformation as in a forging process. The goal of this study is to account fo ...

Deformation mechanism in nanocrystalline FCC metals studied by atomistic simulations

Christian Brandl

Polycrystalline materials with crystallite diameters below hundred nanometer exhibit extraordinary strength which goes along with a decrease in ductility. In order to tailor tough materials, which combine strength and ductility, the underlying deformation ...

EBSD, SEM and FIB characterisation of subsurface deformation during tribocorrosion of stainless steel in sulphuric acid

Marco Cantoni, Stefano Mischler, Emmanuelle Boehm Courjault

The tribocorrosion behaviour of a 304L stainless steel/alumina contact was investigated in sulphuric acid at two imposed potentials (cathodic and passive) The metal deformation below the surface was investigated by analyzing cross sections using secondary ...

STUDY ON HIGH TEMPERATURE DEFORMATION CHARACTERISTICS OF Cu-0.23%Al2O3 DISPERSION-STRENGTHENED COPPER ALLOY

Mingxing Guo

In order to deeply understand the high temperature deformation behaviors of Cu-0.23%Al2O3 (volume fraction) alloy, the changes of flow stress and microstructure for this alloy after deformation at high temperatures were investigated by using the Gleeble-15 ...
