2. 16. Static and time-dependent mechanical behaviour of preserved archaeological wood : Case studies of the seventeenth century warship Vasa

   Author : Alexey Vorobyev; Kristofer Gamstedt; Eiichi Obataya; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; archaeological wood; compression test; cubic samples; elastic constants; oak wood; barrelling formation; quasi-static loading; resonant ultrasound spectroscopy RUS ; Vasa ship; creep; 3D laser scanning; Time-dependent behaviour;

   Abstract : Wooden objects have been widely used in the history of humanity and play an important role in our cultural heritage. The preservation of such objects is of great importance and can be a challenging task. This thesis investigates the static and time-dependent mechanical behaviour of archaeological oak wood from the Vasa warship. READ MORE

4. 17. Structural Integrity Analysis of Critical Elements of RoPax Ships

   Author : Ulf Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety; IACS UR S8; RoRo; experiments; ship collision; RoPax; finite element analysis; event-chain; bow-door;

   Abstract : The potentially costly consequences of a lost ship in the form of fatalities, property, cargo and related industries, as well as pollution of the environment in the form of oil spill, etc., and the public view are the driving forces for developing safer ships. Especially RoRo-ferries, i.e. READ MORE

5. 18. Coining Residual Stresses in Aluminium Ship Structures: Experiments and FE- simulations

   Author : Rutger Ogeman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : 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. READ MORE

6. 19. Ice load prediction for design of ice-going ships for inland waterways

   Author : Meng Zhang; Karl Garme; Magnus Burman; Malin Åkermo; Pentti Kujala; KTH; []
   Keywords : 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;

   Abstract : 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. READ MORE

7. 20. Distributed Participatory Design in Multidisciplinary Engineering Projects: Investigating a Sustainable Approach for Ship Design & Construction

   Author : Steven Mallam; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; User-Centred Design; Naval Architecture; Ergonomics; Built Environment; Maritime; Industrial Design; Knowledge Transfer; Technology Acceptance;

   Abstract : Naval architecture design procedures focus primarily on the technical aspects of engineering specifications, mission requirements and overall survivability of ships and marine structures. In contrast, often little attention or importance is placed on the operational demands of onboard crew and the detailed design characteristics of a ship’s work environment. READ MORE
