The research activities of the professorship deal primarily with the development of efficient numerical calculation methods for structural mechanics, especially for thin structures such as plates, shells and membranes, and their application in structural analysis and various other engineering disciplines. An in-house research code based on the concept of isogeometric analysis (IGA) and the powerful HPC equipment of the attached Laboratory for Engineering Informatics serve as a platform for this.

Another focus is the research and modeling of the material properties of 3D-printed components. The aim here is to be able to precisely predict and optimize the mechanical behavior of the printed materials in order to enable reliable design of additively manufactured components. For this purpose, the Laboratory for Engineering Informatics has been expanded since 2020 to include experimental equipment for 3D printing and material testing.
