Lectures : materials & engineering sciences, fracture mechanics and fatigue of materials - Département de génie Mécanique - http://www.dgm.ens-cachan.fr/ Research : I am a specialist of fracture mechanics and works in the field of defect tolerance design methods in non-linear conditions (inelastic material behaviour, non-isothermal loading conditions, mixed mode crack growth in non-linear conditions, contact mechanics and fretting-fatigue) for aerospace, energy and naval applications. By now, I am developing approaches based on principal components analysis and the thermodynamics of irreversible processes. This method allows to model crack growth, as it is done for the modeling of the non-linear behavior of the materials, but with a formalism based on non-local state variables tailored for characterizing the non-linear behavior of the material around moving singularities such as crack fronts or contact fronts with the minimum possible independent degrees of freedom.
