Fatigue

More than 150 years after August Wöhler's first systematic tests on the fatigue strength of railroad axles, the topic of material fatigue has lost none of its topicality. Whether high-strength steels, light metals, or additively manufactured structures; high cycle numbers under alternating stress quickly reveal weak points in the microstructure of structural materials. Thus, the inspiration for fatigue-resistant materials is as much a topic of the Working Group as the development of new testing methods and measurement techniques as well as the modeling of damage behavior under fatigue loading. Against this background, a two-day meeting of the Working Group Material Fatigue is held every six months at the invitation of industrial companies, research institutes, or universities, with approximately 40 to 70 participants from various areas of applied fatigue research. The Joint Working Group is not only networked within the DGM and the DVM, but also on a European level, e.g. with the Swedish Fatigue Network UTMIS.
