    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Wondmagegn Ergano; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis the aerodynamic loads for maximum power output at acceptable fatigue loads on a 1.5MW onshore wind turbine are examined. LÄS MER

  3. 12. Analysis of length effect dependencies in tensile test for paperboard

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Filip Claesson; [2020]
    Nyckelord :paperboard; short span;

    Sammanfattning : Paperboard combined with polymer and aluminium films are widely used in food packages. Paperboard is used for the bulk of the package material, and provides the stiffness. Paperboard is a highly anisotropic material, which is affected by how the fibers are orientated. LÄS MER

  4. 13. Behaviour of cross laminated timber elements with openings at out-of-plane loading conditions

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Christopher Hast; Daniel Fatemi; [2020]
    Nyckelord :CLT; Cross laminated timber; Grillage model; Gamma method; Bernoulli-Euler beam theory; Timoshenko beam theory; Finite element method; FEM; Composite; Abaqus; Technology and Engineering; Science General;

    Sammanfattning : The use of cross laminated timber (CLT) is expanding, its use is relatively new and universal design standards are lacking. One situation for which no universal design standard exists is that of a CLT plate element with an opening. A grillage method has been proposed as a convenient method to design such plate elements.

  5. 14. Multiscale Analysis of Multifunctional Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ammara Dil; [2019]
    Nyckelord :;

    Sammanfattning : Conventional polymer composites are highly demanding due to their high strength and stiffness, low weight, easy processing and corrosion resistance. However, their weak out of plane properties restricts their use in high performance applications, such as aerospace, military and automotive components. LÄS MER

  7. 15. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Ming Kai Chea; [2019]
    Nyckelord :;

    Sammanfattning : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.
