  1. 16. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

    Master-uppsats, KTH/Betongbyggnad

    Författare :Brook Worku Woldemikael; [2020]
    Nyckelord :Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

    Sammanfattning : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. LÄS MER

  3. 17. Radiell deformation av kamgång i samband med bearbetning

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Anders Wallin; Oskar Andersson; [2020]
    Nyckelord :;

    Sammanfattning : Fordonstillverkaren Volvo Cars i Skövde vill undersöka vilken påverkan skruvförbandet mellan kamlagerhus och cylinderhuvud har på kamgångarnas rundhet. En förberedande genomgång av processflödet genomfördes där varje del isolerades och undersöktes för att identifiera potentiella felfaktorer. LÄS MER

  4. 18. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Nitin Narayanaswamy; [2020]
    Nyckelord :Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

    Sammanfattning : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. LÄS MER

  5. 19. Numerical Assessment of Defects Effect on Boltless Composites Longitudinal Joints

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Mara Santaniello; [2020]
    Nyckelord :;

    Sammanfattning : The work presented in this thesis focuses on the numerical assessment of defects effect on potential boltless design for fuselage panels longitudinal joints, typically identified as High Load Transfer (HLT) configuration. Nowadays, the state-of-art joining technique for primary aircraft composite structures, such as fuselage barrels, is still mechanical fastening. LÄS MER

  7. 20. Thermo-Mechanical Fatigue Assessment of Marine Boiler : Using linear Finite Element Analyses

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Adefemi Samuel Alagbada; [2020]
    Nyckelord :Marine Boiler; FEA; Thermo-mechanical Loading; LEFM; Paris law; Flaws; RAO.;

    Sammanfattning : This thesis is on fatigue crack growth assessments of a thermomechanical loaded Marine Boiler- Sunrod CPDB12. The installation position of the marine boiler in the ship in relation to its fatigue life under mode 1 loading is investigated. LÄS MER
