  2. 16. Ductile failure and rupture mechanisms in combined tension and shear

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

    Abstract : 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. READ MORE

  5. 18. Growth of fatigue cracks subjected to non-proportional Mode I and II

    Author : Peter Dahlin; Mårten Olsson; Veronique École; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue crack growth; Mode II overloading; Crack closure; Sequential mixed mode loading; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This thesis deals with some aspects of crack growth in the presence of cyclic loading, i.e. fatigue. The cyclic load cases studied here are primary of non-proportional mixed mode type. READ MORE

  6. 19. 1-D simulation of turbocharged SI engines : focusing on a new gas exchange system and knock prediction

    Author : Christel Elmqvist-Möller; Hans-Erik Ångström; Daniel Håkansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spark ignited engines; 1-D flow simulation; knock; Divided Exhaust Period; turbocharged engines; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : This licentiate thesis concerns one dimensional flow simulation of turbocharged spark ignited engines. The objective has been to contribute to the improvement of turbocharged SI engines’ performance as well as 1 D simulation capabilities. Turbocharged engines suffer from poor gas exchange due to the high exhaust pressure created by the turbine. READ MORE
