Résumé
On propose un modèle de loi de comportement élastique-viscoplastique basé sur la théorie des dislocations thermiquement activées. On trouve un bon accord entre les prédictions théoriques et les résultats expérimentaux.

Abstract
An elastic-viscoplastic constitutive model based on Thermo-activated theory of dislocation is proposed. Comparision of theoretical prediction and experimental results is in good consistency.
