Abstract

The K I solution for a finite length single-edge notch specimen loaded under fixed-end displacements is derived using a crack compliance analysis. Numerical and experimental checks of the K I solution are provided. Good agreement between the experimental and numerical solutions is observed. The applicability of conventional fracture mechanics to correlate crack growth data generated under displacement control is discussed

Résumé

En utilisant une analyse de compliance, on tire une solution de KI pour une éprouvette à entaille latérale simple de longueur finie soumise à des déplacements imposés sur ses extrémités. On fournit des vérifications numériques et expérimentales de la solution de KI et on constate un bon accord. On discute des possibilités d'appliquer la mécanique de rupture conventionnelle à la correlation de la croissance d'une fissure créée dans des conditions de déplacement contrôlé
