On the way towards a comprehensive failure modelling for industrial sheet metal stamping processes

Abstract

Sheet metal stamping processes are nowadays designed with a high level of standardization. The resulting short development cycles bring by the need for highly efficient simulation software, which are able of delivering unambiguous and reliable formability predictions. This contribution aims making a snapshot of the present state of industrial needs related to this topic and to discuss the possibility for a comprehensive failure modeling approach, able of matching the high standardization requirements. For this purpose the most common failure mechanisms in stamping applications are reviewed and discussed in the context of state of the art modelling approaches. Furthermore the overall qualities required for a comprehensive failure modelling approach in the context of stamping simulation are elucidated and discussed.
