  1. 1. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    University essay from KTH/Materialvetenskap

    Author : Marine Jeanne Debouvry; [2023]
    Keywords : ;

    Abstract : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. READ MORE

  3. 2. Subject-specific image analysis and computational modelling of the human Achilles tendon

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Johanna Panzar; Erika Thörn; [2021]
    Keywords : image analysis; Achilles tendon; FE model; biomechanics; CT image; Technology and Engineering;

    Abstract : Achilles tendon rupture is becoming more prevalent with an increasing population of middle aged people participating in recreational sports. A torn Achilles tendon will likely not regain its original function, and it is unknown what treatment options are optimal. READ MORE

  4. 3. Modeling of Precipitation by Structural Phase-Field Crystal Method

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Jacob Holmberg-Kasa; [2021]
    Keywords : strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

    Abstract : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. READ MORE

  5. 4. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Niclas Elfving; Joel Sunesson; [2021]
    Keywords : Concrete; Creep; Segmentally constructed; Prestressing; Post-tensioning; Viscoelastic; Eurocode; Finite Element; Shell elements; Beam elements; Time-dependant; Steel relaxation.; Technology and Engineering;

    Abstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE

  6. 5. Simulation and Modelling of Injection Molded Components : Fiber Reinforced Polymers in Powertrain Mounts

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Hanna Jakobsson; [2020]
    Keywords : Material modelling; polymer composites; FRP; orthotropic; powertrain mount; vehicle engineering; Digimat; Material modellering; polymera kompositer; ortotropisk; motorupphängnig; Digimat;

    Abstract : Powertrain mounts' purpose is to mount the engine and the gearbox in the car. Besides that, it isolate the body from the powertrain movements and road excitation. The most common material in powertrain mounts bracket is aluminum but lately, fibre reinforced polymer (FRP) has been acting as a substitute for the aluminum. READ MORE
