DFX 2022 33rd SYMPOSIUM DESIGN FOR X
The 33rd DfX Symposium will take place on 22nd & 23rd September 2022 in Hamburg.. DFX 2022 offers young scientists a platform for presenting new ideas and approaches for improving product development.
Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
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.
