Strain nonuniformities and plastic instabilities

... Instabilities can be classified into two main categories which are illustrated by two particular examples: Lüders bands (instabilities of the h type) and the Portevin-Le Chatelier effect (instabilities of the S type)...

...Résumé.- L’auto-organisation des structures de dislocations, des lignes ou bandes de glissement, les instabilités plastiques macroscopiques, constituent, à différentes échelles d’observation, des manifestations typiques d’un comportement coopératif non...

Analyse par thermographie infrarouge des effets dissipatifs de la localisation dans des aciers

... Compared to this first mode (Lüders bands) where dissipative effects are very sudden, intense and strongly localized, we show that zones of mechanical irreversibility leading to localized necking are more...

...déformation.Sur certains aciers doux, on met en évidence la propagation à vitesse uniforme d'une ou plusieurs bandes dissipatives étroites à travers la zone utile de l'éprouvette....

Effects of preferred grain orientation on the on lüders bands appearance... Using the methods of thermography it has been found that at the beginning of the plastic flow Lüders bands occur, pointing to the fact that the preferential grain orientation, in the case of steel with the fine-grained ferrite-pearlite microstructure, has no effect on ...
