Abstract :
[en] The goal of the damage models is the prediction of fracture during forming processes or structural loading after a progressive deterioration of material properties. From all the types of damage (brittle, ductile, creep, fatigue,...), we are particularly interested in the ductile damage, which is associated with large plastic deformation in the neighbourhood of crystal defects. The Gurson model belongs to the coupled approach group, and his strong physical roots has allow a great increase of his use during the last 30 years. In this report a general description of this model, the parameters involved and the finite element implementation in the Lagamine FE code are discussed.
