Abstract
This work aims at the application of local approach to ductile fracture. GTN model is used in order to model damage for different materials. The problem of parameter identification is pointed out. Mesh size dependency of the results is also tackled. GTN model is found to be able to predict ductile fracture for different materials with different damage mechanisms, provided that damage mechanisms are correctly determined: cast iron with high initial void volume fraction, duplex stainless steel with void nucleation as a major part of damage, low alloy steel, with a combination of small initial void volume fraction and void nucleation
