Co-encadrement de la thèse : Laurent Jeanfaivre

High manganese TWIP (TWinning Induced Plasticity) steels are particularly attractive for automotive applications because of their exceptional properties of strength...

X-Ray Diffraction Contrast Tomography (DCT) is a recently developed, non-destructive synchrotron imaging technique which characterizes microstructure and grain...

For the durability analysis of reinforced concrete structures, the modelling of strain localization and the estimation of cracking properties are hot topics. This work...

This thesis falls under an approach of investigation on the damage mechanisms of high zirconia fused-cast refractories. The focus is particularly set on the...

Reinforced concrete structures may have to fulfill functions that go beyond their simple mechanical resistance. During the cracking process, stresses are progressively...

Indentation is a traditional method used to determine the toughness of brittle materials. Different models are used for the calculation depending on the shape of the...

For several years, the MATIERE company has developed a new type of reinforcement based on the use of ribbed flat steel in substitution of high-adhesion round steel...

Que ce soit pour les secteurs de l'aéronautique ou des chaussées dans lesquels ces travaux de recherche s'inscrivent successivement, les structures multicouches, par...

We first revisit the well known framework of Linear Elastic Fracture Mechanics (LEFM) in the case of a fluid-saturated crack. We next consider a r.e.v. of cracked...
