| Abstract Scope |
Despite numerous studies, the prediction of ductile damage and failure during metal forming processes still needs further investigations in particular for complex loading paths. Ductile damage analysis is usually addressed through uncoupled failure criteria or coupled damage models. Both approaches rely either on micromechanical bases or on phenomenological considerations. After a short review of these different approaches, the talk will focus on the main complexities related to damage analysis during metal forming processes. Strain rate and temperature effects, complex multiaxial stress states, non-proportional and cyclic loading conditions will be addressed with examples given at the process scale, whereas a micro-scale finite element framework will also be presented to get a better understanding of some of the physical mechanisms arising in such complex loading conditions. |
