Abstract Scope Due to ecological and economic circumstances the demands regarding efficiency are increasing, especially in the automotive industry. Because of the high material efficiency and the superior mechanical properties, forming technologies still gain in importance. Limitations of conventional forming technologies are expanded by innovative processes and process combinations, such as sheet-bulk metal forming. In a digitized environment this progress is supported by numerical analyses. However, changing boundary conditions represent an enormous challenge for the material characterization and the numerical modelling of forming processes. In sheet-bulk metal forming processes the sheet material typically faces three-dimensional stress and strain states and locally varying effective plastic strain. The three-dimensional material flow is induced to locally adapt the thickness of tailored blanks or to increase the die filling of functional elements, such as gears or carriers. As in every numerical analysis the material characterization and modelling is the foundation for exact results. Beyond the modelling of the forming processes, the measures developed to improve the properties of the components and to enhance the material flow control, in particular, are challenging in the numerical modelling. Holistic investigations in sheet-bulk metal forming are provided within the transregional collaborative research centre 73 the Technical University of Dortmund, the Leibniz University of Hannover and the Friedrich-Alexander-Universität Erlangen-Nürnberg. Current areas of focus are the manufacturing and application of tailored blanks and tailored surfaces, ultrasound assisted forming, development of hybrid approaches and the application of local heat treatment. For the numerical modelling a commercial FE-code is used and extended where necessary.
