  • Beschreibung: The aim of the project was to significantly improve the formability assessment of Advanced High Strength Steel (AHSS) and to improve the reliability of using AHSS in industrial stamping applications. Consequently, a more efficient and thus also economical use of AHSS becomes feasible. The focus of the project is on complex stamping parts, in which sheet material is subjected to stretching and bending simultaneously. First, a comprehensive experimental characterization approach was performed. This included the definition of novel concept test set-ups, a novel strain analysis procedure and the representation of test results with an appropriate method, developed within this project ("failure map concept"). The AHSS failure results of the concept tests are classified according to their failure characteristics with the aim of visualizing the specific AHSS failure patterns. Second, a numerical failure modelling was performed, characterizing the instability of the AHSS sheet material through an instability indicator, based on the number of unstable integration points through the thickness as output of a FEM simulation. Besides that, state of the art failure modelling characteristics are addressed (GISSMO / DIEM). The developed concepts and models are validated with near-industry experiments on selected demonstration parts.
