The modeling approach is based on the so-called micromechanical damage concepts which represent the microstructure evolution more detailed than phenomenological models and, therefore, provide better prediction of damage and failure during the forming process. Particularly, the well-known damage models of Gurson as well as Gologanu-Leblond are considered. It is shown that in combination with fracture criteria such models are able to describe failure in bulk forming.enmetalsbulk formingvoidsdamagefailuresimulations510Prediction of damage in cold bulk forming processesjournal article
