Abstract

Non-linear finite element results from a round robin are compared with empirical and experimental data obtained for three types of geometries: compact specimen, three-point bend specimen and a center-cracked panel subject to uniaxial loading. The solution parameters to be compared in various forms are: applied load, clip gauge displacement, RiceJ-integral (with no limit placed on method of calculation),K 1 crack opening profiles and plastic zone development.

Résumé

Les résultats d'éléments finis non linéaires résultant d'une consultation circulaire sont comparés avec des données empiriques et expérimentales obtenues pour trois types de géométrie: éprouvette compacte, éprouvette de flexion en trois points et panneau à fissure centrale soumis à une charge uniaxiale. Les paramètres de la solution qui doivent être comparés dans les différentes formes sont: la charge appliquée, le déplacement d'un extensiomètre, l'intégraleJ (sans réserve sur sa méthode de calcul), KI, les profils d'ouverture de fissure ainsi que le développement de la zone plastique.
