  1. 16. An evaluation of sustainable designs for trucks : A life cycle analysis

    University essay from KTH/Kraft- och värmeteknologi

    Author : Kim Jaconelli Palm; [2020]
    Keywords : ;

    Abstract : The largest carbon footprint in the life cycle of a truck comes from the use phase. However, with new fuels and larger renewable energy share in the electricity mix, both the manufacture and the disposal phase show increasing weight in carbon emission. A truck consists in large part of steel, which in production generates carbon dioxide. READ MORE

  3. 17. Researching and Developing Universal Gas Purging Solutions

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Ludvig Briheim; Dennis Ståhl; [2020]
    Keywords : Gas Purging Plug; Pipe Purging; Root Shielding; Shielding Gas; Pipe Welding; Rotgasplugg; Rotgasskydd; Skyddsgas; Rörsvetsning; Rörrengöring;

    Abstract : In the welding of more sensitive metals such as stainless steel, titanium and some specific nickel alloys, the presence and application of a protective gas is essential. Without the use of a nonreactive shielding gas, defects occur in or adjacent to the weld joint, which vary from light discoloration of the weld bead to the direct onset and propagation of cracks.

    Abstract : We are facing an important challenge, to reduce the greenhouse gas emissions to make sure that we limit global warming to 2 °C, preferably 1.5 °C. Drastic changes and developing new methods may be our only chance to keep global warming under 1.5 °C. READ MORE

  5. 19. Computational modeling strategy of steel connections

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Carl-Michael Bjälkensäter; Carl Holmgren; [2019]
    Keywords : FEM; steel; connection; joint; Technology and Engineering;

    Abstract : When designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. READ MORE

  6. 20. Experimental study on innovative connections for large span structural timber trusses

    University essay from KTH/Byggnadsmaterial

    Author : Petter Werner Åström; [2019]
    Keywords : Timber structure; timber joint; large span trusses; experimental study; structural timber; birch plywood; reinforcement screws;

    Abstract : Large span timber trusses are usually built with glulam. One problem with large span glulam trusses is that the connections needed to transfer the load between truss members are often complex and expensive. Another issue is transportation. READ MORE
