1. 1. High temperature fatigue crack propagation behaviour of Inconel 718

   Författare :David Gustafsson; Kjell Simonsson; Johan Moverare; Sören Sjöström; Ulrich Krupp; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The overall objective of this work has been to develop and evaluate tools for designing against fatigue in gas turbine applications, with special focus on the nickel-based superalloy Inconel 718. The fatigue crack propagation behaviour under high temperature hold times has been studied. LÄS MER

3. 2. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz

   Författare :Mohamed Sadek; Jens Bergström; Nils Hallbäck; Ulrich Krupp; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very high cycle fatigue; ultrasonic fatigue testing; automotive steels; fatigue strength; stress intensity computation; crack growth; Materialteknik; Materials Engineering;

   Sammanfattning : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. LÄS MER
