Activités de recherche

English:
My current research activities at Icam/ICA are about the damage of composite structures under medium a/o high velocity impacts and crashes: experimental characterization, damage scenario identification, modeling and simulation. In collaboration with Airbus Group, I worked on impact absorption of foam/woven composites shock absorbers optimized with either discrete (stitching, pinning, etc.) or continuous reinforcements (composites walls, etc.).

I currently act as a co-surpervisor of Ir. J.E. Chambe PhD thesis about the design of a composite frame for aircraft seats submitted to crash specifications.

Besides, I have also worked on other aspects in structural dynamics:
- the propagation of uncertainties through dynamical models of assemblies of mechanical structures,
- the shaking of civil engineering reinforced concrete structures subjected to transient dynamic phenomenon,
- the identification until crushing from highly corrupted dynamic tests.


French :
Mes activités de recherche à l'Icam/ICA concernent l'endommagement des structures composites lors d'impacts ou de crashs moyennes et hautes vitesses : caractérisation expérimentale, identification des scénarios d'endommagement, modélisation et simulation. En collaboration avec Airbus Group, j'ai travaillé sur l’absorption d'impact par des absorbeurs de choc mousse/tissus composites optimisés par des renforts discrets ou continus (parois composites, etc.).

Je participe à l'encadrement de la thèse de J.E. Chambe concernant la conception d'un piétement d'un siège d'avion composite sous sollicitation de crash.

Parallèlement, j'ai également travaillé sur d'autres aspects liés à la dynamique des structures :
- la propagation des incertitudes à travers des modèles dynamiques d'assemblages de structures mécaniques,
- la simulation de l'ébranlement des structures de génie civil en béton armé suite à un phénomène transitoire,
- l'identification jusqu'à rupture à partir d'essais corrompus en dynamique.

Activités d'enseignement

My teaching activities are related to the various aspects of structural mechanics:
- continuum mechanics,
- resistance of materials (beam theory),
- dynamics (waves and vibrations),
- finite element modeling,
...
