  1. 21. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels

    Författare :Zhiyuan Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fatigue; stress concentration factor; direct calculation; Container ship; fatigue routing; wave-induced torsion.; extreme loading; nonlinear wave loads;

    Sammanfattning : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. LÄS MER

  3. 22. Design of Powder Core Motors

    Författare :Avo Reinap; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; claw-pole motor; Soft magnetic composite; Electrical engineering; 3D finite element analysis; Elektroteknik;

    Sammanfattning : The goal of the study presented in this thesis is to evaluate the advantages and drawbacks of using powder technology in the design of the iron core of small claw-pole electric motors. The use of soft magnetic composites (SMC) and compaction technology allows the creation of complex 3D iron cores. LÄS MER

  4. 23. RoPax Ship Collision – a Methodology for Survivability Analysis

    Författare :Per Hogström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

    Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER

  5. 24. High capacity timber joints : Proposal of the shear plate dowel joint

    Författare :Gustaf Larsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An increased use of wood can reduce the environmental footprint of the building sector by being a renewable and ecological material. In order to improve the competitiveness of heavy timber structures, this thesis presents a novel type of timber connection with a high degree of prefabrication, which utilizes a resilient bond line.

  7. 25. Effect of fiber reinforcement on fatigue crack growth in fiber metal laminates

    Författare :Per Hofslagare; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Fiber Metal Laminates (FML) are a class of materials with highly resistant fatigue behavior. developed primary for the aerospace industry. The laminates are comprised of alternating layers of high strength alurninum sheet and fiber reinforced polymers. LÄS MER
