Hydrogel coatings are transparent and hydrophilic polymer networks that absorb a lot of water and can be suitable candidates for anti-mist coatings. However, swelling-induced stresses within the film can result in detrimental debonding of hydrogel and may fail. In this study, these debonding processes are investigated in the relation to the graftin...
Cette étude explore l’influence sur le type de sismicité exprimé par le méga-chevauchement des propriétés lithologiques, pétrophysiques et hydrogéologiques des sédiments entrant dans les systèmes de subduction, et de l’évolution de ces propriétés, à partir d’échantillons et de diagraphies issus d’expéditions du Programme International de Découverte...

To explore a local relationship between geological structures and the occurrence of very-low-frequency earthquakes (VLFEs), a particular class of slow earthquakes with characteristic periods of 10–100 s, we investigated three-dimensional (3D) structural features using reprocessed 3D seismic data from the Nankai Trough off Kumano, southwestern Japan...

Flow control of transonic shock wave / boundary layer interactions is investigated in the context of transonic air inlets. A shock wave / turbulent boundary layer configuration with separation zone is considered in the transonic wind tunnel S8. Simulations using Reynolds Averaged Navier Stokes (RANS) and Zonal Detached Eddy Simulation (ZDES, an hyb...

To study the topography of retinal breaks and their agreement with Lincoff's rules. We performed a retrospective descriptive study of patients with recent rhegmatogenous retinal detachments followed on the ophthalmology service of Abass Ndao Hospital from January 2006 through December 2016. Patients with no prior retinal treatment were included. Ov...
The main objective of the present work is to investigate the influence of the microstructure on debond growth along the fiber arc direction. To this end, models of 2-dimensional Representative Volume Elements (RVEs) of Uni-Directional (UD) composites and cross-ply laminates are developed. The Representative Volume Elements are characterized by diff...

Enamel microcrack formation has a high incidence after mechanical debonding of ceramic brackets. This may be due to high delivered shear bond strength values when enamel is priorly etched by phosphoric acid. It is still not well elucidated in the literature if laser etching affects enamel the same way. The aim of the research was to analyze differe...
Le décollement à l’interface constitue l’un des principaux modes de ruine pour les matériaux hétérogènes de type "inclusion-matrice". Du point de vue de la modélisation, il est donc essentiel de décrire le comportement de tels matériaux comportant des interfaces partiellement décollées.Dans le cadre de la mécanique linéaire de la rupture (en élasti...
Le remplacement des couches supérieures des chaussées bitumineuses par des couches à module plus élevé est une technique courante pour augmenter leur durée de vie et intéressante pour les adapter à de nouveaux usages. Parmi les solutions de matériaux existantes, le béton de ciment (cas ponctuel de l’urbain) ou plus communément les enrobés bitumineu...
