  1. 6. Mechanical behavior of Lithium-ion battery electrodes – experimental and statistical finite element analyses

    Författare :İbrahim Buğra Üçel; Peter Gudmundson; Ralf Jänicke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion batteries; mechanical testing; statistics; finite elements; electrodes; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : The applications of Li-ion batteries in the electronics and vehicle industry is increasing at a very rapid pace. This is primarily due to superior properties such as high specific energy storage and power as well as wider operation temperature ranges. LÄS MER

  3. 7. Generation of Patient Specific Finite Element Head Models

    Författare :Johnson Ho; Svein Kleiven; Michael Gilchrist; KTH; []
    Nyckelord :Injury Prevention; Patient Specific; Finite Element Head Model; Anatomical Structures; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Traumatic brain injury (TBI) is a great burden for the society worldwide and the statisticsindicates a relative constant total annual rate of TBI. It seems that the present preventativestrategies are not sufficient. To be able to develop head safety measures against accidents ine.g. LÄS MER

  4. 8. 3D Finite Element Modeling of Cervical Musculature and its Effect on Neck Injury Prevention

    Författare :Sofia Hedenstierna; Hans von Holst; Peter Halldin; Jac Wismans; KTH; []
    Nyckelord :Finite Element; Cervical Musculature; Neck injury prediction; Continuum Mechanics; Solid Elements; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Injuries to the head and neck are potentially the most severe injuries in humans, since they may damage the nervous system. In accidents, the cervical musculature stabilizes the neck in order to prevent injury to the spinal column and is also a potential site for acute muscle strain, resulting in neck pain. LÄS MER

  5. 9. Modeling of plasticity at large strains

    Författare :Mathias Wallin; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is concerned with various aspects of the constitutive modeling of plasticity. Both theoretical issues and issues related to the numerical implementation of the constitutive models are addressed. LÄS MER

  7. 10. Development and application of corotational finite elements for the analysis of steel structures in fire

    Författare :Luca Possidente; Jean-Marc Battini; Nicola Tondini; Paulo Vila Real; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermomechanical finite element; Shell element; 3D beam element; Steel structures; Buckling; Fire Safety Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : The ignition and the propagation of a fire inside a building may lead to global or local structural collapse, especially in steel framed structures. Indeed, steel structures are particularly vulnerable to thermal attack because of a high value of steel conductivity and of the small thickness that characterise the cross-sections. LÄS MER
