Détermination d’un protocole pour la construction d’un modèle en éléments finis d’un fémur à partir des images CT

Dans ce projet, nous cherchons à définir un protocole ainsi que les points à améliorer pour créer un modèle d’éléments finis à partir des images CT d’un fémur cadavérique. La première étape, qui inclut la segmentation et le lissage de la géométrie, sert à ...

When manufacturing capability exceeds control capability: The paradox of high precision products, or is it possible to assemble functional products out of components we are unable to measure?

Jacques Jacot, Fabien Bourgeois, Sandra Koelemeijer Chollet

Sorting and mating is a very common practice in high precision manufacturing, as well in the watch industry, biomedical or automotive industry. This strategy helps to increase the assembly yield, but is costly and time-consuming. The question is, when is i ...

FEM-MILL: a finite element based 3D transient milling simulation environment for process plan verification and optimization

Jitender Kumar Rai

The rigid body motion of thin walled parts and their elastic-plastic deformations induced during high speed milling are the main root causes of part geometrical and dimensional variabilities; these are governed mainly from the choice of process plan parame ...

Sub-100 nm-scale Aluminum Nanowires by Stencil Lithography: Fabrication and Characterization

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena, Katrin Sidler Arnet

We present the fabrication process and electrical characterization of sub-100 nm scale Al nanowires (NWs) fabricated by stencil lithography (SL). We use a stencil with sub- 100 nm wide nanoslits patterned by focused ion beam (FIB) milling. The stencil is a ...
