Abstract
The model of Lemaitre and Chaboche (LC) (1990) is investigated in the context of a study of ductile fracture of copper by void growth and co alescence. The paper illustrates the fact that a phenomenological mode l such as the LC model based on a mesoscopic damage variable is not we ll suited for predicting fracture because it cannot account for the co mplexity of the void coalescence process localised at the microscale.
