Structural health monitoring (SHM) of materials is a fundamental measure to master thedurability and the reliability of structures in service. Beyond the industrial...

The aim of this work is to study the nano-scale deformation mechanisms within the spherulitic structure of semi-crystalline polymers. The deformation mechanisms are...

In order to design reliable concrete structures, prediction of long term behaviour of concrete is important. In fact, creep deformation can cause mechanical...

Experimental studies in a hydrogeneous environment indicate that hydrogen created by surface reactions, then drained into the plastic zone, leads to a modification of...

This thesis was focused on cavitation damage in rubbers submitted to gas decompression. Previous studies have shown cavities appearance in elastomers when a level of...

Concrete is a complex heterogeneous material whose deformations include a delayed part that is affected by a number of factors such as temperature, relative humidity...

Although they are potentially sensitive, energetic materials are designed to be stable under normal conditions, as well as "weak" mechanical, chemical or thermal...

In the context of geological disposal of radioactive waste, this work contributes to the characterization of the effect of diffuse damage on the water retention and...

The electron beam welding of 7xxx series alloys leads to modification of their microstructure and consequently of their mechanical behavior. This study aimed to...

Les travaux présentés dans ce mémoire portent sur l'analyse mathématique de modèles dissipatifs en mécanique des milieux continus. Une attention est portée sur des...

The work of modeling presented here relates to the study of the thermo-hydro-mechanical behaviour of porous materials based on hydraulic binder such as concrete, High...

The AA6061-T6 aluminum alloy was chosen as the material for the core vessel of the future Jules Horowitz testing reactor (JHR). The objective of this thesis is to...

The need to predict the mechanical behavior of reinforced concrete industrial structures and assess their level of damage in extreme conditions under the action of...

This study is part of the AMUFISE project (ANR, program " Matériaux Fonctionnels et Procédés Innovants") driven by the Michelin manufacture. It is focused on the study...

Dans le domaine industriel, les calculs non-linéaires prennent actuellement une part de plus en plus importante dans le processus de conception des structures. La...

Chromia-former alloy are mainly used for high temperature applications. Their ability to form a protective thermal oxide scale allows reducing oxidation kinetics of...

The integrity of cell membranes is essential for their survival and for the proper functioning of the cell. However, these membranes are constantly exposed to damage....
