Sheet-bulk metal forming is an innovative method for the manufacturing of functional components by applying bulk metal forming processes or combined sheet and bulk metal . Measurement procedures, which are generally used for geometrical quality control of sheet metal and bulk metal forming parts, are very similar, but none of these methods . Sheet-bulk metal forming (SBMF) processes are defined as forming of sheets with an intended three-dimensional material flow as in bulk forming processes (Merklein et al. 2012).As semifinished product, sheets with an initial thickness of 1–5 mm are used and subjected to one or several conventional bulk forming operations. An alternative approach, proposed in the recent last two decades, to predict the localized neck prior to fracture in sheet or bulk metal forming, is the full coupling between the material's behavior and the ductile damage using either macroscopic monoscale or micro–macro multiscale modeling approaches as can be found in the recent books .

Sheet-bulk metal forming is defined as forming of sheets with an intended three-dimensional material flow as in bulk forming processes [3]. The skew symmetric tensor W ^ ̲ p = [F ˙ ^ ̲ p F ^ ̲ p-1] A defines a certain measure of the plastic spin which reduces to the total spin W ̲ = [F ˙ ̲ F ̲-1] A with the small elastic strain assumption. Note that the superscripts [ The book discusses the challenges posed by simulating sheet–bulk metal forming. It takes into account the different phenomena characteristic to both sheet and bulk forming fields, and explores the demands this makes on modelling the processes. It then summarizes the research, and presents from a practitioner's point of view. .

For the separation of the influence of the sheet geometry from that of the forming of multiple parts on one sheet, only one forming operation is carried out per blank or coil. Consequently, the forming is symmetrical on the X and Y-axis, which is why the radii in –X- and Y-orientation according to Fig. 12 are evaluated.

Due to increasing economic and ecological restrictions, conventional sheet and bulk forming operations often reach their limits with regard to part weight and functional integration. One solution to meet those challenges is provided by sheet-bulk metal forming (SBMF) processes. SBMF is defined as the application of bulk forming operations on sheet . The resulting parts from sheet metal forming are relatively high in strength and malleability. Comparatively sheet metal forming is a more cost-effective process than other conventional sheet metal processes. Various metals can be processed through sheet metal forming such as aluminum, copper, brass, and steel.
