Variational theory of Cosserat arches and affine tensors
Géry de Saxcé
Our purpose is to revisit the screw theory in light of the affine tensor formalism, introducing the co-momentum and momentum tensors. Our target-applications of the Euler-Poincaré…
A family of variational principles of minima for the plasticity, the friction contact and the fracture mechanics
Géry de Saxcé
The paper is a synthesis of several works on the variational principles for application to the mechanics and the physics, inspired from original ideas of Brezis, Ekeland and Nayrol…
Cosserat media in dynamics
Géry de Saxcé
Our aim is to develop a general approach for the dynamics of material bodies of dimension d represented by a mater manifold of dimension (d + 1) embedded into the space-time. It ca…
Symplectic bipotentials
Mohammad Harakeh, Michael Ban, Géry de Saxcé
In a previous paper, we proposed a symplectic version of Brezis-Ekeland-Nayroles principle based on the concepts of Hamiltonian inclusions and symplectic polar functions. We applie…
Symplectic and variational formulations of compressible and incompressible Navier-Stokes equation
Géry de Saxcé
In a previous paper, we proposed a symplectic version of Brezis-Ekeland-Nayroles principle based on the concepts of Hamiltonian inclusions and symplectic polar functions. We illust…
A non incremental variational principle for brittle fracture
Géry de Saxcé
The aim of the paper is to propose a paradigm shift for the variational approach of brittle fracture. Both dynamics and the limit case of statics are treated in a same framework. B…
