  1. 6. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Jessica Jacobs; [2021]
    Keywords : ;

    Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

  3. 7. Impact of wood fibers on the mechanical performance of biocomposite materials

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Keywords : Biocomposite; Composite; X-ray tomography; Image analysis; Injection moulding; Fracture mechanisms; Technology and Engineering;

    Abstract : 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. READ MORE

  4. 8. Examination of a Damaged Slitting Knife using Scanning Electron Microscopy and Finite Element Simulations

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Love Öman; [2021]
    Keywords : slitting; slitting knives; damage; sem;

    Abstract : At voestalpine Precision Strip AB, the slitting process is used frequently. Slitting is a commonly applied manufacturing technique during sheet metal processing that aims to split large coils of sheet metal into narrower widths. READ MORE

  5. 9. Life and fracture in very high cycle fatigue of a high strength steel

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Daniel Karlsson; [2021]
    Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE

  6. 10. Dynamic Finite Element Modelling of a Fall on the Hip

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Nils Nyberg; [2021]
    Keywords : Hip Fracture; Finite Element Modeling; Finite Element; Femur Fracture; Sideways Fall; Technology and Engineering;

    Abstract : Assessing the risk of future femur fracture is an important step in preventing this serious and common injury. The current methods to predict the fracture risk are typically based on bone mineral density measurement, used as a surrogate for femoral strength. READ MORE
