Utilisation de la microscopie acoustique pour l'�tude des propri�t�s locales du bois : �tude pr�liminaire de param�tres exp�rimentaux

Abstract: Résumé -Pour comprendre le comportement macroscopique du bois, il est intéressant de connaître ses propriétés à l'échelle microscopique. Pour cela, diverses techniques d'imagerie nous donnent des informations sur la structure géométrique en deux ou trois dimensions, la composition chimique, la densité ainsi que la présence de réseaux cristallins et leurs orientations. Les propriétés méca-niques sont souvent estimées, soit par des essais sur fibre isolée, soit par modélisation à partir des données de rigidité d… Show more

“…Studies have shown that to size up the operational ultrasound frequency, a compromise must be made between resolution and penetration, which are two important parameters to be considered to ensure the quality of the characterization. Indeed, the resolution increases as the frequency goes up high; in the same time, the penetration decreases as the frequency increases (Berson et al, 1994;Clair et al, 2000). Characterization of an environment or a structure can be *Corresponding author.…”
