International audience; The purpose of this paper is to experimentally validate a 1D probabilistic model of damage evolution in unidirectional SiC/SiC composites. The key point of this approach lies in the identification and validation at both local

This paper presents a methodology for multiscale coupling between the morphology and texture of a microstructure as has been characterised experimentally, and the results of mechanical strain field analysis. This methodology is based on a coupling be

Au cours des operations de soudage des toles de zirconium, l'elevation de temperature conduit a l'apparition d'un gradient microstructural dans la structure soudee, entrainant un gradient de caracteristiques mecaniques. Pour une vitesse de refroidiss

This study aims to determine the different deformation mechanisms of grade 702 zirconium under uniaxial tension and at room temperature. The grade 702 zirconium tested had undergone an {alpha} {yields} {beta} {yields} {alpha} cycle at a slow cooling

Image noise is an important factor that influences the accuracy of strain field measurements by means of digital image correlation and scanning electron microscope (SEM) imaging. We propose a new model to quantify the SEM image noise, which extends
