  1. 21. Structural analysis of the 17th century warship Vasa : Influence of the dowels on the stiffness of the hull

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Marina Muñoz García; Juan Carlos Hurtado Sierra; [2014]
    Keywords : Vasa; Wasa; FEA; dowel; hull; deformation; support;

    Abstract : After 333 years under depths of the Baltic Sea, the warship Vasa was salvaged and nowadayslies in a dry dock inside the Vasa Museum in Stockholm. Its current support system, which consists on eighteen cradle-stanchions pairs of steel, is not able to handle the present loads in a satisfactory manner. READ MORE

  3. 22. Fluid Structure Interaction Modeling of the Dynamic of a Semi Submerged Buoy

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Shatha Hameed Hajwal; Hamza Zeidan Nasser; [2013]
    Keywords : COMSOL Multiphysics; wave energy converter; Dynamic characteristic; Submerged body; Finite Element method FE ; SDOF; ALE.;

    Abstract : This thesis presents a study of buoy systems for wave’s energy by focusing on the development of a model in which modeling of a wave energy conversation is in operation. Throughout the thesis, the buoyancy and motion of the submerged body has been used to describe the wave-buoy interaction. READ MORE

  4. 23. Effect of axle load spreading and support stiffness on the dynamic response of short span railway bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Annelie Syk; Erik Axelsson; [2013]
    Keywords : short span railway bridges; dynamic response; finite element analysis; load spread; support stiffness; korta järnvägsbroar; dynamisk respons; analys med finita element; lastspridning; stödstyvhet;

    Abstract : In this thesis the effect of axle load spreading through ballast and the effect of support stiffness has been investigated on short span railway bridges. Two types of bridges, simply supported bridges and bridges with integrated backwalls, have been modeled with 2D beam elements. READ MORE

  5. 24. Characterisation of laminated glass for structural applications

    University essay from Linnéuniversitetet/Institutionen för bygg- och energiteknik (BE)

    Author : Shaheda T. Akter; Mohammad Khani; [2013]
    Keywords : Laminated glass; PVB; Sentry Glass; Bending stiffness; Bending strength;

    Abstract : Laminated glass (LG) consists of two or more glass layers bonded by an elasto-polymeric layer, the most commonly used being PVB (Polyvinyl Butyral). LG has improved safety properties compared with single layer glass because the interlayer prevents large sharp pieces from spreading when the glass is broken by impact. READ MORE

  6. 25. Influence of the ballast on the dynamic properties of a truss railway bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Lucie Bornet; [2013]
    Keywords : Ballast; Railway bridges; Experimental dynamics; Finite element modelling; Natural frequencies; Eigenmodes; Bridge stiffness.;

    Abstract : To deal with a rapid development of high-speed trains and high-speed railways, constant improvement of the railway infrastructure is necessary and engineers are continuously facing challenges in order to design efficient and optimized structures. Nowadays, more and more railway bridges are built and thus, they require the engineers’ attention both regarding their design and their maintenance. READ MORE
