Developments for the Production of Local Foamed Hollow Sections
The investigation of the basic principles for the production of foamed out sections using magnesium foam for support structures by including the foaming process into the cold forming of sections to produce indiviually locally strengthened components is the subject of this research project. To absorb tensile stress, the metal foam will be strengthened with three-dimensional branched struts of high-tensile materials. The quantification of the influence of locally introduced foaming elements on e.g. stiffness alterations and the influence of the resonance frequency of the total structure will be effected by destructive but particularly also by nondestructive tests.
