The 35th Design for X Symposium (DFX 2024)
DfX offers young scientists from the field of product development a platform for presenting new ideas and approaches to their research. (Registration is now OPEN)
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:
Fibre-reinforced plastics are increasingly being used in important structural components. Here they are often subjected to cyclic loading, which leads to a deterioration in material properties. However current design methods hardly take this fatigue behavior into account. Instead, they rely on conservative safety factors, resulting in over-dimensioned components. In order to realise the full lightweight potential, we propose an innovative method that enables a targeted design for a defined service life. It integrates knowledge from experimental fatigue testing and uses modified mathematical failure criteria to predict the degree of fatigue throughout the part. This allows us to adaptively reinforce fatigue critical areas, resulting in lightweight and fatigue resistant structures.
