  1. 1. Micromechanical Characterization of Thin Paper Materials

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Linus Bengtsson; [2023]
    Nyckelord :Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

    Sammanfattning : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. LÄS MER

  3. 2. Material Characterization and Blade Impact Simulation

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

    Författare :Gustaf Bodare; [2022]
    Nyckelord :Strain rate dependency; Split-Hopkinson pressure bar; Digital image correlation; LS-DYNA; FEM; SPG;

    Sammanfattning : Blades used on brushcutters and lawn mowers are subjected to a wide variety of working conditions. Besides continuous loads from cutting grass, the blades are also subjected to accidental impacts of branches, stones and structures. LÄS MER

  4. 3. Sensor concepts for Industry 4.0

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Daniel Le; [2021]
    Nyckelord :Fluorescence; alumina; ruby; piezo-spectroscopic effect; Technology and Engineering;

    Sammanfattning : The next industrial revolution has been denoted by Industry 4.0 and is the continuation of the process of knowledge acquisition and further control over the entire production process which has been evolving since the beginning of the industrialization. A paramount driver of Industry 4.0 is the smart sensor. LÄS MER

  5. 4. Numerical study of the effect of thermal ice loads on concrete dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Imal Zuwak; Wasseem Kordoghly; [2020]
    Nyckelord :Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Sammanfattning : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. LÄS MER

  7. 5. Basic Creep of Young Concrete - Sensitivity in the Evaluation Method

    Master-uppsats, KTH/Betongbyggnad

    Författare :Benar Ekmat; Natalea Hermes; [2019]
    Nyckelord :thermal cracking; young concrete; creep; Linear Logarithmic Model; temperature development; average strain; sensitivity.; Temperatursprickor; ung betong; krypning; Linjär Logaritmisk Modell; temperaturutveckling; töjning; känslighet.;

    Sammanfattning : Creep is defined as deformation that takes place under constant load after an initial elastic response. This thesis focuses on a material property problem area that concerns stress analysis. Focus is on stress development considering creep deformations occurring when a concrete structure is under load, i.e. LÄS MER
