Etude de l’influence des défauts de petite taille sur le comportement à rupture avec le modèle de Dugdale
Keywords:
fracture, Dugdale’s model, scale effect, limit loadsAbstract
The goal of this work is to prove that, within the framework of Fracture Mechanics with Dugdale model of cohesive forces, the defects the size of which are small compared to the material characteristic length are practically without influence on the limit loads of structures. For that, we treat two cases: first, we solve in a closed form the case of a precracked plate, then we compute by using the finite element method the response of a plate with a circular hole.
