Modern light weigth concepts are characterised by a specific application of tailored materials, new production technologies as well as complex components. This work, dealing with the hydroforming of complex frame structures made of Tailor Welded Blanks, faces up therefore one of the main topics of lightweigth. Aim of this work was on the one hand the fundamental investigation of sheet hydroforming applied to frame structures, in order to define suitable process strategies and process limits with the support of analytic and numeric methods. On the other hand the potential of sheet hydroforming as a forming technology for Tailor Welded Blanks should be considered, aiming at the definition of general process design strategies for the production of a complex frame structure.
