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…
