  1. 1. Shape stability of laminated veneer products

    Författare :Lars Blomqvist; Dick Sandberg; Jimmy Johansson; Magdalena Sterley; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adhesive; beech; birch; bending; laminated veneer products; moulding; shape stability; spring-back; twist; veneer; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : This thesis is about the shape stability of laminated veneer products.Laminated veneer products consist of veneers bonded together with adhesive into a predetermined shape. Such products are used in several contexts but especially in furniture manufacture. LÄS MER

  3. 2. Numerical simulation of sheet metal forming for high strength steels

    Författare :Claes Arwidson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : New demands for passenger safety, vehicle performance and fuel economy have led to an increase in the use of advanced high strength steel. An increase in strength decreases the formability of the material and increases the spring back behaviour. LÄS MER

  4. 3. Monitoring Single Tooth Cutting Forces in Wood Bandsawing

    Författare :Vanessa Meulenberg; Dick Sandberg; Daniel Chuchala; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : For economic and environmental benefits, sawmills can reduce their waste by sawing with thinner bandsaw blades. When altering the cutting tooth geometry, it is vital to monitor the sawing process in realistic wood conditions such as frozen (green), non-frozen (green) and dried. LÄS MER

  5. 4. Robustness Analysis of Residual Stresses in Castings

    Författare :Magnus Hofwing; Niclas Strömberg; Mårten Olsson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis is about robustness analysis of residual stresses in castings. This topic includes the analysis of residual stresses in castings and the robustness analysis itself, both covered in the thesis. Residual stresses are important when designing casted components.
