The issue of the GTN parameters identification requires further investigations, taking into account different materials, stress states, loading rates. This will provide the list of typical GTN parameters, useful for engineers to perform strength analysis of structural members prior to failure. Regardless of the f F value, simulations clearly indicate that the GTN model is suitable for modeling structural elements prior to destruction, and describing material softening, associated with changes in the material microstructure due to large plastic deformation.
