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…
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 symplectic Brezis-Ekeland-Nayroles principle
Marius Buliga, Gery de Saxce
We propose a modification of the hamiltonian formalism which can be used for dissipative systems. This work continues arXiv:0810.1419 and advances by the introduction of a symplect…
Affine Tensors in Mechanics of Freely Falling Particles and Rigid Bodies
Gery de Saxce, Claude Vallee
In a previous paper, we proposed an approach for the dynamics of 3D bodies and shells based on the use of affine tensors. This new theoretical frame is very large and the applicati…
