Mesure de rigidit\u00e9 Kokak<\/h2>\n

Principe de la mesure de rigidit\u00e9 par r\u00e9sonance.<\/p>\n

D\u00e9finie par la norme ISO 5629 en 1983 qui s’intitule :
\nPapier et carton — D\u00e9termination de la r\u00e9sistance \u00e0 la flexion — M\u00e9thode par r\u00e9sonance<\/p>\n

Nous n’expliquerons pas les principes physiques qui sont \u00e0 la base de cet instrument (secret de fabrication oblige).<\/p>\n

La premi\u00e8re fabrication par Adamel Lhomargy est r\u00e9alis\u00e9e sous licence Kodak Path\u00e9.<\/p>\n

Nous avons repris le dossier d’origine pour \u00e9laborer cet instrument.<\/p>\n

Les am\u00e9liorations apport\u00e9s permettent une mesure plus rapide et pratique.<\/p>\n

Principe :<\/p>\n

On mesure la longueur d’un bande \u00e9chantillon de papier qui vibre sous une fr\u00e9quence d\u00e9termin\u00e9e.<\/p>\n

La lecture de la rigidit\u00e9 Kodak est directe mais on peut aussi calculer le module d’Young du mat\u00e9riau.<\/p>\n
