  1. 1. Ductile failure and rupture mechanisms in combined tension and shear

    Författare :Imad Barsoum; Jonas Faleskog; Björn Skallerud; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : This licentiate thesis is generally concerned with the ductile failure and rupture mechanisms encountered under combined tension and torsion loading. In the first part entitled Paper A, an experimental investigation of the rupture mechanisms in a mid-strength and a high strength steel was conducted employing a novel test configuration. LÄS MER

  3. 2. The effect of stress state in ductile failure

    Författare :Imad Barsoum; Jonas Faleskog; Viggo Tvergaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile failure; Rupture mechanisms; Stress triaxiality; Lode parameter; Finite element analysis; Experiments; Localization; Micromechanics; Void growth; Void coalescence; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : The industrial application of high strength steels in structural components has increased the demand on understanding the ductile failure behavior of this type of materials. In practical situations the loading experienced on components made out of these materials can be very complex, which may affect the failure behavior. LÄS MER
