  4. 3. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

    Författare :Valbona Mara; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

    Sammanfattning : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. LÄS MER

  5. 4. Torque and Angle Controlled Tightening of Bolted Joints

    Författare :Göran Toth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torque controlled tightening; deformation parameters; momentary elongation; deformation factor; torque; Bolted screwed joints; spring characteristic; Torx; torque and angle controlled tightening; hexalobular; final torque; snug torque; Taylor’s series expansions; preload; plastic deformation; permanent elongation; yield; friction diameter; plastic spring constant; clevis; turn-of-nut method; bearing surface pressure; twisting; Monte-Carlo simulations;

    Sammanfattning : Reduced weight and fuel consumption, improved reliability and engine performance are the main requirements in the automotive industry of today. These requirements demand robust and optimized bolted joints, where a high amount of preload obtained by effective utilisation of the bolt is essential. LÄS MER

  7. 5. Enhanced Composite Joint Performance through Interlacement of Metal Inserts

    Författare :Sahar Akbarpour; Stefan Hallström; Conor McCarthy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace Engineering; Flyg- och rymdteknik;

    Sammanfattning : The work in this thesis investigates bolted joints in fibre reinforced composites with particular focus on a novel insert concept. The concept is characterised by replacing all composite plies with stacked metal patches, locally around a bolt hole, so that they jointly form a solid metal reinforcement. LÄS MER
