Abstract
An analytical method is derived to determine the tearing resistance of a material using the double-cantilever-beam specimen. The analysis makes use of a beam-on-elastic foundation model to determine the elastic deflection of the specimen and the Dugdale model to simulate the stress field at the crack tip.J resistance curve of 2024-T3 aluminium material is obtained based on the experimentally observed load and crack extension and is compared with those deduced using compliance method and finite element method.
Résumé
On déduit une méthode analytique permettant de déterminer les résistances d'un matériau à l'arrachement, en utilisant une éprouvette en double poutre Cantilever.
L'analyse fait appel à un modèle de poutre sur appuis élastiques en vue de déterminer la flèche élastique de l'éprouvette, et au modèle de Dugdale en vue de simuler le champ de contraintes à l'extrémité de la fissure.
Une courbe de résistance, exprimée parJ, est obtenue dans le cas de l'alliage d'aluminium 2024-T.3, en se basant sur les observations expérimentales de la charge appliquée et de l'extension de la fissure; cette courbe est comparée avec celles que l'on obtient en utilisant une méthode de compliance et une méthode par éléments finis.
