Preserved Fulltext
The aim of our work is the modeling of the damage in the weld metal according to the finite element method and the concepts of fracture mechanics based on local approaches using the code ABAQUS calculates. The use of the Gurson-Tvergaard-Needleman model axisymmetric specimens AE type to three different zones (Base metal, molten metal and heat affected Zone) with four levels of triaxiality (AE2, AE4, AE10 and AE80), we have used to model the behavior of damage to welded steel, which is described
