  1. 21. 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. 22. Validation of Finite Element Model of a Tetra Pak Package

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Nyckelord :Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Sammanfattning : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  4. 23. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Elina Fernö; [2023]
    Nyckelord :Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Sammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER

  5. 24. Efficient FE Modeling of Large Casted Parts

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Nyckelord :FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Sammanfattning : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. LÄS MER

  7. 25. Exploring Disaster Impacts on Climate Mitigation Policy Change in Latin America

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Lotte Petersen; [2023]
    Nyckelord :natural hazards; disaster; climate mitigation policy; latin america; policy change;

    Sammanfattning : This study aims to empirically explore if there is an association between climate-related disasters and climate mitigation policy change in middle-income countries. This is important for understanding future climate mitigation policy, as disasters are predicted to increase in both frequency and severity. LÄS MER
