Shape parameter estimation of a 3D model from multi-view radiographic images

High pressure turbine blades in aircraft engines are exposed to extreme thermal and mechanical conditions.They withstand them through multiple innovations, which demand strict controls to be carried out during their production.Among the Non…

De la sensibilité accélérométrique des oscillateurs optoélectroniques à la mesure dynamique de déformations dans les fibres optiques

Optoelectronic oscillators (OEO) are an alternative solution to traditional quartz oscillators for high purity frequency references generation. For the most demanding applications, the phase noise performances must be kept in harsh vibration…

Détermination des mécanismes de dégradation de poumons humains sous chargement de blast et critères lésionnels associés

Lung damage is the leading cause of death in the face of a blast. For protection purposes, it is essential to understand the causes of this damage. For the moment, the effects of this shock wave on the lungs are poorly described. Indeed, in the…

Étude de la cinétique de séchage des bétons : Application à l'atteinte d'un gradient hydrique représentatif dans le cadre des essais au feu

Spalling of concrete is one form of the thermal instability induced by fire exposure. It needs to be investigated when the fire behaviour of structures is to be assessed.Fire behaviour is commonly assessed by reference to the requirements of NF EN…

A projection-based approach to extend digital volume correlation for 4D spacetime measurements

In-situ (tomography) experiments are generally based on scans reconstructed from a large number of projections acquired under constant deformation of samples. Standard digital volume correlation (DVC) methods are based on a limited number of scans…

Identification and validation of constitutive parameters of a Hencky-type discrete model via experiments on millimetric pantographic unit cells

Pantographic metamaterial design benefits from model identification procedures starting from what can be considered as the elementary unit cell of larger pantographic structures. Results from a tensile experiment and digital image correlation are…
