Le principal objectif de ce travail est l'étude de la fragmentation d'enveloppes métalliques. Cette thèse est divisée en quatre parties : la construction d'un modèle d'endommagement, l'implémentation numérique, la calibration des paramètres du modèle en utilisant des données expérimentales, et des travaux analytiques.Tout d'abord, nous avons considéré des modèles qui couplent les modèles d'endommagement classiques avec la plasticité et la dynamique. En utilisant l'énergie et l'action du système, nous avons obtenu toutes les équations qui décrivent le modèle dynamique et ductile : l'équation de la dynamique, le critère de plasticité et le critère d'endommagement. Nous avons ensuite détaillé l'implémentation numérique de ces modèles.Des résul...
