Sheet Metal Formability Testing with DIC Part I For Evolving Automotive Materials_2022-03_FADI-AMT

Despite the introduction of new classes of lightweight materials and manufacturing techniques, “stamping” of steel sheets is still the dominant manufacturing approach for mass production of automotive body structures. That being said, there are still many new grades of steel and high strength aluminium alloys that are progressively introduced to the sector, thus posing evolving challenges both in terms of manufacturing and material characterization for forming simulations (FEA). In this webinar, we shed some light on the topic of “material formability” with focus on the automotive sector. We cover the main formability testing approaches and how they are used to test the wide range of automotive materials. Beyond conventional steels, particular emphasis will be made to addressing the needs of the industry in testing the latest generations of advanced high strength steels and aluminium alloys. Digital image correlation (DIC) is of critical importance to formability testing, thus we dedicate a portion of this webinar to the integration of DIC with formability testing, and the use of DIC to extract FLC points via different algorithms/approaches.
