Ce travail présente une méthode mixte expérimentale-numérique traitant des mesures mécaniques réalisées sur structures pour l’identification de propriétés matériau viscoélastiques linéaires. Les caractéristiques de ces matériaux sont complexes et dépendent de la fréquence et nous cherchons à les identifier par une approche directe et non paramétrique. Pour cela, deux méthodes d’identification adaptées au traitement des mesures de champs de réponses en fréquences sont présentées. Cellesci utilisent les données fréquentielles, sans analyse modale expérimentale. Les champs expérimentaux sont obtenus par vibromètrie laser et les champs numérique par la méthode des éléments finis. Nous utilisons un modèle volumique adapté à l’étude des structure...
