1. 1. Projection Nut Welding to High- and Ultra-high Strength Steels

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Love Englund; [2023]
   Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

   Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER

3. 2. En teoretisk modell för 3D-printing av fälg i kolfiber

   M1-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Författare :Samuel Hall; [2022]
   Nyckelord :3D-printing; Carbon fiber; Carrim; Automotive wheels;

   Sammanfattning : The automotive industry faces the challenge to manufacture vehicles with reduced material usage and climate impact. To achieve this the industry has begun using other materials such as carbon fibre composite than materials such as steel and aluminium which are normally used for the manufacturing of automobile parts.

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. The influence of post-buckling damage on the tensile properties of single wood pulp fibers

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Raphael Andreolli; [2021]
   Nyckelord :Solid Mechanics; single fiber testing; wood pulp fibers; post-buckling damage; experiments; development of testing methods; tensile properties; tensile stiffness; tensile strength; Hållfasthetslära; enskild fiber testning; pappersmassa fiber; skada efter knäckning; experiment; utveckling av testutrustning; dragegenskaper; dragstyvhet; draghållfasthet;

   Sammanfattning : The rapid growth of plastic waste from food packaging around the world demands renewable substitutes, such as natural fibers and biocomposites. Wood fibers are natural fibers extracted from trees and are commonly used in packaging. LÄS MER

7. 5. Tensile strength reduction for insufficient thread engagement A FEM study of a wall-shoe assembly

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Henrik Larsson Sevon; [2021]
   Nyckelord :Solid Mechanics; Tensile strength; Wall-shoe; Thread engagement; Hållfasthetslära; Draghållfasthet; Väggsko; Gängingrepp;

   Sammanfattning : The purpose of this master thesis is to determine whether or not it exist, a model that can describethe reduction in strength, due to missing threads in a bond between a bolt and nut. And how thereduction in strength might effect a wall-shoe assembly, used to connect a wall to another wall or aconcrete base plate. LÄS MER
