Abstract

The aim of our work is the modeling of damage in the welded metal using the finite element method and the concepts of fracture mechanics based on local approaches. The use of Gurson-Tvergaard-Needleman (GTN) model has enabled us to model the behavior of damage of welded steel, which is described as being due to the growth of cavities.
