  1. 1. Exploring the Possibilities of Sheet Metal Forming Via Plastic-Based Additive Manufacturing Moulding

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Jemal Idris Ismail; Kafeel Olanrewaju Sanni; [2023]
    Nyckelord :: Sheet metal formation; Additive manufacturing; mass customization; personalized production; die design; die system; FDM; DOE; FEA; product development; automotive; sustainability; cost effective; metal dies; plastic dies.; Plåtformning; Additiv tillverkning; massanpassning; personlig produktion; formdesign; formsystem; FDM; DOE; FEA; produktutveckling; fordonsindustri; hållbarhet; kostnadseffektiv; metallformar; plastformar.;

    Sammanfattning : Additive Manufacturing (AM) has freeform fabrication capabilities of complex geometries directly from feedstock material. This can potentially enhance the efficient use of material and the cost effectiveness. It also offers design flexibility, and it is versatile. LÄS MER

  3. 2. Framtagning av en Vakuumisolerad kryotank

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Linus Höber; [2022]
    Nyckelord :kryotank; vakuumisolerad; flytande väte; Umeå universitet;

    Sammanfattning : I dagens samhälle är flygplan det snabbaste och ibland ett livsviktigt transportmedel. Med nutidens teknologi är det inte möjligt att tillverka ett passagerarflygplan som drivs av el då det skulle bli för tungt. Elen produceras av bränsleceller som drivs av vätgas. LÄS MER

  4. 3. Simulations of experimental crack development in ceramic material with notched specimen

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Clas Dahlin; [2022]
    Nyckelord :Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Sammanfattning : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. LÄS MER

  5. 4. Moment-resisting connections for glulam using birch plywood : An experimental study on both mechanical and adhesive connections

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Jonatan Ringaby; [2022]
    Nyckelord :;

    Sammanfattning : The aim of this study was to investigate the load-bearing capacity and stiffness of mechanical and adhesively bonded connections in timber structures with gusset plates made of birch plywood, as a preliminary study for potential future use in long-span timber structures which could reduce the environmental impact of the building sector by substituting steel with wood products in moment-resisting connections. Birch plywood was chosen for this study due to its high bending strength in comparison to plywood made of softwoods and its availability on the market. LÄS MER

  7. 5. Crosslinked Cartonboard - Challenges and possibilities

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Malin Elvin; [2022]
    Nyckelord :Cartonboard; crosslinking; mechanical properties; SCT;

    Sammanfattning : The need for sustainable packaging is growing, and plastic waste needs to be reduced. A suitable alternative could be fibre-based packaging and cartonboard, and several actions could enhance this alternative. This study investigates crosslinking, a method to create stronger bonds between the OH-groups in the material. LÄS MER
