[Sur des critères de chargement en plasticité]
Les critères de chargement dans la formulation dans l'espace des déformations de Lagrange pour la plasticité indépendante du taux de déformation sont comparés à deux autres types de conditions, celle de Nguyen et Bui et celle du type Kuhn–Tucker. Quand ces dernières sont exprimées entièrement dans l'espace des déformations, leur relation au critère de chargement en formulation d'espace de déformations devient transparent.
The loading criteria of the Lagrangian strain-space formulation of rate-independent plasticity are compared with those of Nguyen and Bui and those of Kuhn–Tucker type. When the latter two sets of conditions are expressed in a fully strain-space form, their relationship to the loading criteria of the strain-space formulation becomes transparent.
