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 coalescence. The paper illustrates the fact that a phenomenological model such as the LC model based on a mesoscopic damage variable is not well suited for predicting fracture because it cannot account for the complexity of the void coalescence process localised at the microscale.
