    Sammanfattning : Rapid climate changes have increased the importance of environmental concerns,particularly within the construction industry, which faces substantial challenges to reduceits environmental footprint. Shifting from high-emission building materials to sustainablealternatives stands as a critical strategy to reduce climate impact. LÄS MER

  2. 2. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Shivang Parmar; [2023]
    Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER

  3. 3. Embedment Behavior of Steel Dowel in Timber Loaded Perpendicular to the Grain : Influence of Assembly History in Combination with Moisture Change and Cyclic Loading

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Mojtaba Khalili; [2023]
    Nyckelord :Embedment strength; elastic and plastic embedment stiffness; moisture content; swelling and shrinkage; steel dowel; assembly history; cyclic loading;

    Sammanfattning : The embedment behavior of dowels in timber structures, as an essential parameter in the design of connections, is the subject of this thesis. There are numerous advantages using timber structures, including sustainability, energy efficiency, and aesthetic appeal. LÄS MER

  4. 4. 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

  5. 5. Validation of An Iteration Free Material Model for Paperboard (NEO)

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

    Författare :Samuel Thomas Staines; [2022]
    Nyckelord :Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Sammanfattning : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. LÄS MER
