  1. 16. Computational weld mechanics : Towards simplified and cost effective FE simulations

    Författare :Ayjwat Awais Bhatti; Zuheir Barsoum; Lennart Josefson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : It is the demand of the world’s ever increasing energy crisis to reduce fuel consumption wherever possible. One way of meeting this demand is by reducing the weight of a structure by replacing thick plates of low strength steel with thin plates of high strength steel in the structure. LÄS MER

  3. 17. Coining Residual Stresses in Aluminium Ship Structures: Experiments and FE- simulations

    Författare :Rutger Ogeman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The build-up and redistribution of residual stresses obtained by stress coining of aluminium plates containing a hole have been studied experimentally and numerically. The foil strain gauge technique has been employed to measure strains at the bore of a hole during and after the coining process. LÄS MER

  4. 18. Computational weld mechanics - Increased accuracy in fatigue assessment, distortion and residual stress analysis

    Författare :Jinchao Zhu; Zuheir Barsoum; Mansoor Khurshid; Rami Mansour; Heikki Remes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational weld mechanics; fatigue assessment; weld distortion; residual stress; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : This thesis work is concerned with the mechanical response of welded steel structures, which are distortions, residual stresses, and fatigue. The accuracy of fatigue assessment, distortion and residual stress analysis using Computational weld mechanics (CWM) is focused. LÄS MER

  5. 19. Residual Stress Analysis and Fatigue of Welded Structures

    Författare :Zuheir Barsoum; Jack Samuelsson; Jan Langkjear Hansen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; fatigue; finite element analysis; fracture mechanics; residual stresses; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This licentiate thesis is generally concerned with the fatigue of welded structures. Several topics related to fatigue of welded structures are treated such as; weld defects and their influence on fatigue performance of welded structures, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, welding simulation, residual stress prediction and measurement and their influence on fatigue.

  7. 20. On some Fatigue Problems Related to Steel Bridges

    Författare :Roberto Crocetti; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modular bridge expansion joints; full-scale testing; web breathing; postbuckling behaviour; fatigue; riveted connections;

    Sammanfattning : This thesis concerns three specific fatigue topics related to steel members in bridges, namely: (1) Modular Bridge Expansion Joints (MBEJs). Several premature fatigue failures of MBEJs have occurred in Europe and USA during the past decades. LÄS MER
