The working group Materials is aimed equally at the subprojects from the process-side as well as material characterizing subprojects. Material characterisation forms an important basis for process design in sheet-bulk metal forming and for the description of the components' properties. The primary objective of the working group is to combine the investigations of different subprojects on material behavior and to support the exchange of information on the investigation methods used.
