Ce travail de thèse porte sur l'étude de l'intégration des fonctions d'amortissement vibroacoustique dans des plaques en matériau composite. Dans un premier temps, pour une méta-plaque non composite, les caractéristiques d'atténuation des vibrations ont été étudiées avec un réseau périodique de résonateurs (poutre-masse) attachés à une plaque.L'effet de périodicité et des résonances locales permet de bloquer la propagation d'ondes sur des plages de fréquences données, appelée bandes interdites. Des simulations numériques basées sur la MEF ont permis de calculer les diagrammes de bandes des plaques périodiques et d'analyser la sensibilité de ces bandes interdites aux différents paramètres de conception de méta-plaque. Les calculs de coeffici...
