Jedes Modul umfasst 3 ECTS. Sie wählen insgesamt 10 Module/30 ECTS in den folgenden Modulkategorien:
- 12-15 ECTS in Technisch-wissenschaftlichen Modulen (TSM)
TSM-Module vermitteln Ihnen profilspezifische Fachkompetenz und ergänzen die dezentralen Vertiefungsmodule. - 9-12 ECTS in Erweiterten theoretischen Grundlagen (FTP)
FTP-Module behandeln theoretische Grundlagen wie die höhere Mathematik, Physik, Informationstheorie, Chemie usw. Sie erweitern Ihre abstrakte, wissenschaftliche Tiefe und tragen dazu bei, den für die Innovation wichtigen Bogen zwischen Abstraktion und Anwendung spannen zu können. - 6-9 ECTS in Kontextmodulen (CM)
CM-Module vermitteln Ihnen Zusatzkompetenzen aus Bereichen wie Technologiemanagement, Betriebswirtschaft, Kommunikation, Projektmanagement, Patentrecht, Vertragsrecht usw.

The course deals with fundamental and technical issues associated with designing and maintaining structures that resist failure from cyclic loading. Students will be taught the principles of fatigue testing and analyzing fatigue failures of materials, addressing the questions of how fatigue behaviour is characterized, how fatigue failure is predicted, which physical mechanisms are responsible for fatigue initiation and propagation in various materials, with particular attention to metals and structural alloys, and how such behaviour is related to the microstructure of the material.
This course will also introduce key applications of fatigue design in industry, including failure analysis, fatigue life calculations, experimental techniques and destructive and non-destructive methods of damage detection and characterization.
