  1. 1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  3. 2. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olivia Karlsson; [2022]
    Nyckelord :Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

    Sammanfattning : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. LÄS MER

  4. 3. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Jijesh Rajan; [2022]
    Nyckelord :Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Sammanfattning : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. LÄS MER

  5. 4. Impact of wood fibers on the mechanical performance of biocomposite materials

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

    Författare :Jose Maria Moreno Ivañez de Lara; [2021]
    Nyckelord :Biocomposite; Composite; X-ray tomography; Image analysis; Injection moulding; Fracture mechanisms; Technology and Engineering;

    Sammanfattning : Plastics are amazing materials with outstanding properties that make them very useful and cheap for a wide range of uses. However, their pollution to the environment has become one of the main problems to solve in this century. In this Master Thesis biocomposites from Biofiber Tech are studied. LÄS MER

  7. 5. Utredning av sprickorsakerna i infästningarna till kylelement

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Ammie Bäckström; Nicklas Werner; [2021]
    Nyckelord :;

    Sammanfattning : The assignment handed out by Cementa in Skövde is to investigate why crack formation and propagation emerge in the fixed attachment clamps and propose solutions against it. The fixed attachments are part of the cooling element suspension, used in the cement production to cool the material coming out of the oven. LÄS MER
