Influence of the roughness of sandblasted surface on the measurement of hardness by nanoindentation, Influence de l’amplitude de la rugosité de surfaces sablées sur la mesure de dureté par nanoindentation

Hsin Shen Ho, Yang Xia, Julie Marteau, Maxence Bigerelle

Nanoindentation tests are often used to characterize the surface mechanical properties of materials. However, this technique lacks repeatability: when different zones of the same specimen are tested, there can be large differences between the nanoindentation curves. One of the main causes is the…, Les essais de nanoindentation sont souvent utilisés pour caractériser les propriétés mécaniques des matériaux en proche surface. Cependant, cette technique manque de reproductibilité : une même réponse mécanique est difficilement obtenue par les essais de nanoindentation sur différentes zones de la…

Bone texture analysis is correlated with three-dimensional microarchitecture and mechanical properties of trabecular bone in osteoporotic femurs

Thomas Le Corroller, Martine Pithioux, Fahmi Chaari, Benoit Rosa, Sebastien Parratte, Boris Maurel, Jean-Noël Argenson, Pierre Champsaur, Patrick Chabrand

Fracture of the proximal femur is a major public health problem in elderly persons. It has recently been suggested that combining texture analysis and bone mineral density measurement improves the failure load prediction in human femurs. In this study, we aimed to compare bone texture analysis with…

A new automatic image registration algorithm based on corner detector for remote sensing applications

Lila Meddeber, Tarik Zouagui, Abdelmalik Taleb-Ahmed, Nassreddine Berrached

In this paper, we propose a new automatic satellite image registration approach capable of handling remotely sensed images geometrically distorted by various transformations such as translation, rotation, and shear. This technique exploits the invariant relations between regions of a reference…

3D Modelling of Thermal Replication for Designing Progressive Glass Moulds

Dominique Lochegnies, Philippe Moreau, Fabienne Hanriot, Patrick Hugonneaux

Worldwide, ESSILOR International provides customers with Progressive Addition Lenses (PAL), which replace bifocal lenses. Thermal replication is one process to produce glass moulds for PAL, using sagged glass on a ceramic slumping block. In this paper, thermal replication for producing PAL glass…

Towards large time simulation reduction for the solving of mechanical contact (large scale) problems: A robust control approach

Antonio Gonzalez Sorribes, Jimmy Lauber, Thierry-Marie Guerra, Franck Massa, Thierry Tison

The evolution of computational resources contributes to the use, more and more frequent, of mechanical contact in numerical models. The main difficulty is to determine rapidly the contact loads which allow balancing two structures, modeled by the finite element method. This problem is reported to…

FEM Simulation Based on CAD Model Simplification: A Comparison Study between the Hybrid Method and the Technique Using a Removing Details

Mounir Hamdi, Nizar Aifaoui, Borhen Louhichi, Abdelmajid Benamara, Dominique Deneux

The simulation process is currently used in the design and dimensioning of mechanical parts. With the progress of computer materials, the Finite Elements Method (FEM) becomes the most used approach in the simulation of mechanical behavior. The simulation process needs multiple Design-FEM loops. In…
