Volume is indexed by Thomson Reuters BCI (WoS).The demands now being made on metallic structures are increasingly complex, since the strains and application loading-profiles which occur are locally limited and inhomogeneous. Therefore, high-strength structures having optimised material properties have to be developed.Based upon the research goals and target problems of Collaborative Research Centre 675, mass laws and process models are investigated which clearly and predictably relate materials and processing parameters to characteristic property values, shapes and dimensions.

Volume is indexed by Thomson Reuters BCI (WoS).The demands now being made on metallic structures are increasingly complex, since the strains and application loading-profiles which occur are locally limited and inhomogeneous. Therefore, high-strength structures having optimised material properties have to be developed.Based upon the research goals and target problems of Collaborative Research Centre 675, mass laws and process models are investigated which clearly and predictably relate materials and processing parameters to characteristic property values, shapes and dimensions. In this work, development and manufacturing processes are considered and integrated; beginning from the original choice of material, going via the scaling-up of local material properties and leading right up to the creation of the final manufactured component.Funded by the German Research Foundation, this research project investigates materials and processes for forming, manufacturing, and joining high-strength structures, and their effect on desired component properties. Topics of the 13 papers include martensite evolution during sheet metal forming, the production of foamed hollow sections, superimposed cold solid forming, 3D optical measurement with locally adapted projection, and fatigue life calculation for structures with inhomogenous strength properties.
