The design of sandwich structures is challenging due to the large number of constituents and materials used. Existing design approaches do not include the consideration of the occurring initial damage as well as application-oriented boundary conditions in testing and optimization. Therefore, a general approach to the design optimization is presented consisting of the four parts problem definition, physical test, virtual test and design optimization, as well as an initialization phase and subsequent iterations. An exemplary application is performed for the novel design concept of optimizing the geometry of the core filling. From the initial results, the potential of the new design approach becomes clear, which can be used as a basis for the design optimization of any sandwich structures.
