This paper deals with the finite element modeling of the pressure vessel with two artificial internal surface cracks, one positioned in the vessel center and the other one close to the vessel cover. Cracks are made by electroerosion, with radius at the tip 0.1 mm. The pressure vessel has been experimentally investigated to determine strain distribution by suitably positioned strain gages along smooth portions of the path for J integral direct measurement, as the first phase of the structural integrity assessment procedure. In order to verify numerical procedure, different finite element models are used, one complex model with two cracks and two simple models, each with a single crack. Boundary conditions are identified as the most difficult...
