Modélisation de la plasticité due à une transformation martensitique dans les aciers / Modelling of plasticity caused by a martensitic transformation in steelsMeftah, Salem 26 October 2007 (has links)
Cette thèse porte sur l'analyse d'un phénomène particulièrement important dérivant des conséquences mécaniques des transformations de phases solide-solide dans les aciers : la plasticité de transformation ou TRIP (Transformation Induced Plasticity) et son interaction avec la plasticité classique. Ce sujet est abordé à la fois par des investigations expérimentales et par une approche de modélisation numérique, pour les transformations martensitiques. / This thesis concerned with the analysis of a particularly important phenomenon which corresponds to one of the mechanical consequences of solid-solid phase transformations in steels: the transformation plasticity or TRIP (TRansformation Induced Plasticity) and its interaction with classical plasticity. This subject is addressed from the point of view of experimental investigations as well as with a nuimerical modelling approach, concerning martensitic transformations.
