Other people naturally can be added to the list of the founders, among them, in France, Jacques Louis Lions, Haim Brézis, and Roland Glowinski in maths, Georges Duvaut, Nguyen Quoc Son, Bernard Nayroles, Olivier Débordes, Michel Jean, Pierre Suquet in mechanics ...
Nonsmooth Mechanics
Roughly speaking, non-smooth dynamics is the branch of mechanics that deals with dynamical systems governed by non-smooth laws. Common examples are unilateral constraints, friction, impact, plasticity, damage, brittle failure, etc. My main theoretical interest in this area is the numerical aspect of the sweeping process. The sweeping process is a powerful concept, both mathematical and mechanical, introduced by Jean Jacques Moreau.

Main topics
Main topics of research on Non Smooth Dynamical Systems (NSDS):
- Moreau's sweeping process and unbounded differential inclusions
- Complementarity systems, variational inequalities
- Higher order systems with unilateral constraints
- Nonsmooth Mechanics, multibody dynamics with contact, impact and friction : mechanisms, granular materials
- Nonsmooth Electronics, electrical circuits with ideal components
- Numerical time-integration of non-smooth dynamical systems
- Numerical solvers for discrete variational inequalities and complementarity for the 3D frictional contact problem and plasticity
- Non-convex and non-smooth constitutive laws of materials (coupling contact and friction with cohesion and surfacic damage)
Applications, valorization and transfer
