The aim of this working group is to evaluate the performance of the components produced in the research areas dependent on component damage. Here, it is necessary to establish a connection between the damage characterized in research area B and the component behavior when being in use. A corresponding methodology for quantifying performance will be developed in cooperation with research areas A and B. The methods for determining the performance are adapted to the respective demonstrators as they are exposed to different loads in use. While extruded parts show primarily static operating loads (bending, torsion, etc.), sheet metal components are rather dynamically loaded.
The methods to be developed extend the assessment options of performance by instrumented multi-stage fatigue tests which are carried out in project B01 during the first funding period in cooperation with research area A. Bent and deep-drawn parts, for example, are examined in simplified crash tests in this working group. Methods for assessing performance (vibrations, bends, etc.) are also being tested for bulk metal forming. The result is an assessment of the performance depending on the damage and the forming history.
An essential task of this working group, which is headed by project B01, is to establish and describe the connection between process, microstructure, and performance. The results are to be published in the form of joint publications of the working group and will also serve as preparatory work for the second funding period, during which the performance is to be specified and quantified.
