  1. 1. Utvärdering av larmgränser för extensometermätningar vid bergbyggande : En fallstudie vid Henriksdals reningsverk

    Master-uppsats, KTH/Byggvetenskap

    Författare :Jesper Spång; [2022]
    Nyckelord :Rock engineering; Alarm limits; Extensometers; Failure probability; Rock mass deformation; Bergbyggande; Larmgränser; Extensometrar; Brottsannolikhet; Deformation av berg;

    Sammanfattning : Vid en ombyggnation av Henriksdals reningsverk har ett vertikalschakt utformats och anlagts. Under berguttaget tillämpades extensometermätningar för att följa upp deformationer i en bergpelare mot en befintlig tunnel. Mätningar utfördes automatiserat och regelbundet. LÄS MER

  5. 4. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Emil Edin; [2019]
    Nyckelord :Ti-6Al-4V; LMwD; Characterization; Alpha Laths;

    Sammanfattning : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. LÄS MER

  7. 5. Polymer Aging Mechanics : An investigation on a Thermoset Polymer used in the Exterior Structure of a Heavy-duty Vehicle

    Master-uppsats, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Basil Abu-Ragheef; [2019]
    Nyckelord :polyDicyclopentadiene; aging; thermosets; fatigue; mechanical properties; thermal fatigue; digital image correlation; viscoelasticity; polymer degradation; thermo-oxidation; photo-oxidation;

    Sammanfattning : The use of plastic materials in the design of vehicle components is primarily driven by the need for vehicle weight and cost reduction. Additionally, these materials give design engineers freedom in creating appealing exterior designs. LÄS MER
