  1. 1. Mechanical design guidelines and criteria for mooring components in wave energy devices : Finding the optimum chain and shackle parameters

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Arvin Modiri; [2022]
    Nyckelord :Chain; shackle; finite element method; wave energy converter; WEC; Kedja; kätting; schackel; finita element metoden; vågkraftverk;

    Sammanfattning : Obtaining the perfect renewable energy source is one of the most important questions of our lifetime. One renewable energy source that could be of interest in this question because of the characteristics of the power that could be extracted from it is wave energy. LÄS MER

  3. 2. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Gunnar Dufwa; [2022]
    Nyckelord :Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Sammanfattning : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. LÄS MER

  4. 3. In-vivo imaging of root growth in response to localized mechanical stress

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Leah Eitelberg; [2022]
    Nyckelord :kinematics analysis; time-lapse imaging; root growth rate; root curvature; soil heterogenety; local mechanical stress;

    Sammanfattning : By taking up nutrients and water, root growth has an important influence on plant growth and productivity. Thereby, root growth is influenced by its surrounding soil conditions, which vary spatially even on a small scale. Hence, different parts of the root system are exposed to different penetration resistances in the soil. LÄS MER

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

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Jessica Jacobs; [2021]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 5. The Identification of Collagen Failure in Vascular Tissue

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kathryn Dennisson; Nicole Namousi; [2021]
    Nyckelord :;

    Sammanfattning : Aortic diseases are a common and fatal health issue, regarding various conditions targeting the aorta. The arterial wall consists of two proteins; collagen and elastin (fibers), and they will contribute to the elasticity and strength of the wall. LÄS MER
