Numerical determination of the forming limit diagram for thin sheet metal foil from a ductile damage model identified via Micro-Single Point Incremental Forming tests

Résumé

In this paper, the micro-formability of thin sheets is investigated by a numerical approach. A coupled elastic-plastic-damage model is used to predict forming limit diagram according to the micro-Marciniak tests. The identification of the ductile damage model is first performed from micro-single point incremental forming tests using inverse finite element method. Finally, both the micro-forming limit curve and the micro-forming limit stress curve are plotted.
