Abstract
JR-resistance curves obtained on a C-Mn steel with different specimens are compared. The experiments confirm a geometrical dependence of the fracture toughness. An attempt is made to explain these results in terms of models derived from the local approach to fracture. Two types of model are presented where the damage is, either uncoupled or coupled to the material behaviour. The uncoupled model with the Tai-Yang approach and the coupled model with the Rousselier potential give results in good agreement with the experiments.
