    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Very High Cycle Fatigue; Stainless steel; Ultrasonic fatigue testing; Crack initiation; Crystallographic crack growth; Distributed Dislocation Dipole Technique; Closed cracks; Materialteknik; Materials Engineering;

    Sammanfattning : Mechanical fatigue is a failure phenomenon that occurs due to repeated application of mechanical loads. Very High Cycle Fatigue (VHCF) is considered as the domain of fatigue life greater than 10 million load cycles. LÄS MER

  3. 2. Very high cycle fatigue of duplex stainless steels and stress intensity calculations

    Författare :Muhammad Waqas Tofique; Jens Bergström; Nils Hallbäck; Anders Gåård; Johan Moverare; Karlstads universitet; []

    Sammanfattning : Very high cycle fatigue (VHCF) is generally considered as the domain of fatigue lifetime beyond 10 million (107) load cycles. Few examples of structural components which are subjected to 107-109 load cycles during their service life are engine parts, turbine disks, railway axles and load-carrying parts of automobiles.
