    Sammanfattning : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. LÄS MER

  4. 3. Methods for the Evaluation of Wingsails with a Crescent-Shaped Profile

    Författare :Heng Zhu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-assisted ship propulsion; rigid wingsail; light weight structure; crescent-shaped profile; wind-assisted ship propulsion.;

    Sammanfattning : Seaborne transportation accounts for a large proportion of greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has stipulated that GHG emissions should be reduced by 50% before 2050 compared to 2018. The use of wind-assisted ship propulsion (WASP) is considered one of the most effective ways to reduce GHG emissions. LÄS MER

  5. 4. Ice load prediction for design of ice-going ships for inland waterways

    Författare :Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inland waterway ship; ice load; ice conditions; ice properties; FSICR; probabilistic method; ice-hull interaction; numerical model; structural response; finite element analysis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : With increasing interest in utilizing the inland waterways (IWW) in European countries, the design of IWW vessels gains attention both from a transport efficiency and an emission control point of view. However, unlike in western and central European countries, in Nordic countries, e.g. LÄS MER

  7. 5. Failure of thinwalled structures under impact loading

    Författare :Salar Mostofizadeh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thinwalled shell structures; cohesive zone; phantom node method; ductile failure; XFEM;

    Sammanfattning : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. LÄS MER
