Résumé

L’émission acoustique est une technique largement utilisée pour l'étude de l'endommagement des matériaux. Si, dans la littérature, un intérêt particulier est porté sur l'énergie libérée durant les mécanismes de rupture, force est de constater que peu d'attention est accordée à la variation dans le temps des discontinuités locales créées lors de ces mécanismes. L'objet du présent travail est de dégager l'influence des caractéristiques dynamiques des processus de rupture sur l'amplitude des signaux d'émission acoustique.
