[Quelques inégalités de type Poincaré pour les champs de matrices quadratiques]
We present some Poincaré-type inequalities for quadratic matrix fields with applications e.g. in gradient plasticity or fluid dynamics. In particular, applications to the pseudostress–velocity formulation of the stationary Stokes problem and to infinitesimal gradient plasticity are discussed.
On présente quelques inégalités de type Poincaré pour les champs de matrices quadratiques, avec des applications, par exemple, en plasticité avec gradients ou en dynamique des fluides. En particulier, on discute des applications pour la formulation en vitesse de pseudo-tension du problème stationnaire de Stokes et pour la plasticité infinitésimale avec gradients.
