The goal of this work is to prove that, within the framework of Fracture Mechanics with the regularized Dugdale’s 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 examples : the case of a precracked plate, then the case of a plate with a circular hole. The calculations are made with the finite element method.
