Ce travail a pour but d'étudier la variation des modes propres d'une section de l'aorte en fonction de la nature des couches et de la géométrie. On se place dans le...

This thesis is divided in two parts. The main tool of this work is time optimal control. We first consider the Pontryagin maximum principle for control system of...

This thesis is motivated by the modelling and the simulation of fluid-structure interaction phenomena in the vicinity of heart valves. On the one hand, the interaction...

The objective of this thesis is to study the ability of model reduction for investigations of flow-induced vibrations in heat exchangers tube bundle systems.These...

This work presents a full scale experimental study on the aero-elastic wind/sails/rig interaction in real navigation condition with the aim to give a reliable database...

We here investigate the modeling of fluid-structure interactions. The fluid is viscous and inscompressible and the structure is subject to an imposed deformation....

In this thesis we focus on the numerical analysis and the development of efficient partitioned algorithms for fluid-structure interaction (FSI) problems arising in...

In several industrial applications, the vibrating structures are in contact with a fluid (fluid around the hulls of a boats, reservoirs, heat exchangers in power...

It is well established that concrete durability strongly depends on the capillary porosity of the material. Hence, structural health monitoring of concrete structure...

The work summarized in this memoir stem from one of the following two topics: the modeling and numerical simulation of coupled systems (Chapters 1-3) and the...

This thesis contributes to the verification and the validation of the Baer-Nunziato (BN) model, to modelize water ham- mer phenomena in industrial piping systems. It...

This thesis is devoted to the mathematical study of the swimming at low Reynolds number. The controllability and the optimal problems associated with the displacement...

This study deals with the coupling between an incompressible, irrotational fluid and an elastic container in the context of small amplitude vibrations.Firstly, we...

The thesis studies the response of a flat plate coupled with a liquid and submitted to an expanding pressure field created by a detonation. A detonation is the most...

The design of flexible lifting bodies in the naval industry, such as propelleror rudders, create some new design problems. This thesis proposes a numerical method...

We present macroscopic models of the mechanical behavior of the human lung's parenchyma obtained by the two--scale homogenization method. The first part focuses on the...

Ce mémoire présente quelques contributions à la prise en compte de diverses conditions limites ou d'interface lors de la résolution de problèmes par la méthode des...
