The Collaborative Research Centre 666 develops methods, processes and facilities with the aid of which branched structures in integral sheet metal construction can be optimized with regard to their function and stress. The research activities are aimed at new methods of developing multifunctional products and completely new manufacturing possibilities. In the area of product development, new methods of algorithmic product development involving mathematical optimization and graph theory are being developed.
Subproject A02: Mathematical models and algorithms for an automated product development of branched sheet metal products
The aim of subproject A02 is to combine experience-based product development and mathematical optimization techniques with regard to automated product development of branched sheet metal structures in order to increase the degree of automation within product development and to offer the designer a decision-making aid. For this purpose, the descriptions of the constructive components are to be formulated as optimization problems and efficient solution methods for automated product development are to be designed.

Subproject A06: Simulation-based optimization methods for the deep drawing of branched structures
In this subproject, numerical methods for the optimization of the deep drawing processes of sheet stringers are developed. Based on a finite element simulation of the deep drawing process, selected process parameters, such as blank holder forces and fluid pressure in hydroforming, locking forces in the flange area, shall be optimized subject to constraints of strains and buckling stresses with respect to a given objective function, e.g., maximal material flow or position of sheet stringer.
