  1. 6. Rate-dependent effects on the mechanical behaviour of paper

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Satyasarathi Poddar; [2023]
    Nyckelord :;

    Sammanfattning : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. LÄS MER

  3. 7. Embedment Behavior of Steel Dowel in Timber Loaded Perpendicular to the Grain : Influence of Assembly History in Combination with Moisture Change and Cyclic Loading

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Mojtaba Khalili; [2023]
    Nyckelord :Embedment strength; elastic and plastic embedment stiffness; moisture content; swelling and shrinkage; steel dowel; assembly history; cyclic loading;

    Sammanfattning : The embedment behavior of dowels in timber structures, as an essential parameter in the design of connections, is the subject of this thesis. There are numerous advantages using timber structures, including sustainability, energy efficiency, and aesthetic appeal. LÄS MER

  4. 8. Effekterna på mekaniska egenskaper hos PLA filament efter återvinning

    Uppsats för yrkesexamina på grundnivå,

    Författare :Mohamed Mohamed; Domian Yonan; [2022]
    Nyckelord :;

    Sammanfattning : Fused deposition modeling (FDM) is a quick developing additive manufacturing (AM) technology because of its ability to construct functional practical elements with complicated geometries. AM enables the design of complex three-dimensional (3D) objects by depositing materials layer by layer. LÄS MER

  5. 9. Conditioned 3D-printed polyamides for structural optimization : Establishing the material data to advance in AM utilization

    Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Philip Olsson; [2022]
    Nyckelord :Additive manufacturing; selective laser sintering; multi jet fusion; moisture; temperature;

    Sammanfattning : Polyamides are commonly used in additive manufacturing for final part production, but the material performance can be affected by environmental conditions. The purpose of this project was to evaluate the effects of moisture and temperature on 3D printed polyamides and how structural optimization can benefit from condition-specific data. LÄS MER

  7. 10. Timber pile-supported road embankment : Numerical and analytical analysis of field monitoring project E4 Råneå

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

    Författare :Kent Nystedt; [2022]
    Nyckelord :Geosynthetic reinforcement; Geosynthetic reinforced pile supported embankment; Pile distance; Embankment height; Finite element method; Pile efficacy;

    Sammanfattning : The previous E4 Råneå road embankment was prone to flooding. Risk of flooding in combination with settlements of the road due to the weak underlying sulphide soil was problematic. The Swedish Transportation Administration improved the length section E4 Råneå by rebuilding the road using the method light embankment piling. LÄS MER
