  1. 21. Experimental Characterization of Electrodes and Multi-Scale Modeling of Swelling Induced Stresses in Lithium-ion Batteries

    Författare :Priyank Gupta; Peter Gudmundson; Göran Lindbergh; Erik Olsson; Elham Sahraei; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium-ion batteries; mechanical characterization; multiscale modeling; homogenization; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. LÄS MER

  3. 22. Creep aspects of softwood from the cell-wall level to structures

    Författare :Rhodel Bengtsson; E. Kristofer Gamstedt; Mahmoud Mousavi; Reza Afshar; Falk Wittel; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Creep; Solid Mechanics; Wooden Materials; Linear Viscoelasticity; Experiments; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER

  4. 23. Ultra high-pressure compaction of powder

    Författare :Sven Berg; Javier Oliver; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Sintering at high-pressure improves the properties of the material, either through new sintering aids becoming available or through improving intergranular bonding. This gives the manufactured products potential advantages like faster cut rates, and more precise and cleaner production methods that add up to cost efficiency and competitive edge. LÄS MER

  5. 24. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    Författare :Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. LÄS MER

  7. 25. On the fracture behaviour of softwood : a combined experimental and computational study of the interaction between fracture behaviour and material anatomy

    Författare :Lars Olof Jernkvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. LÄS MER
