  1. 21. Fatigue crack initiation and propagation in sandwich structures

    Författare :Magnus Burman; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The focus throughout this thesis is on the fatigue characteristics of core materials used insandwich structures. Three sandwich configurations are investigated, two with cellular foamsand one with honeycomb core material These corresponds to typical materials and dimensionsused in the marine and aeronautical industry.

  3. 22. Molecular mechanisms of local anaesthetic action on voltage-gated ion channels

    Författare :Johanna Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In this thesis I try to clarify some molecular mechanisms of local anaesthetic action on ion channels. The traditional view is that local anaesthetics eliminate action potentials by a direct block of Na channels. Other mechanisms, however, have been suggested. LÄS MER

    Författare :Marianne Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Numerical modelling; Factorial DOE; Stochastic simulation; Accident reconstruction; MADYMO; Child Safety; Restraint system; Anthropometry; Q3;

    Sammanfattning : Traffic related trauma is the main cause of child fatality and injury in Europe and North America, with the large majority of fatalities and injuries occurring to children in cars. Specifically, head injury is a common outcome in injury causing car accidents. LÄS MER

  5. 24. A Study on Structural Cores for Lightweight Steel Sandwiches

    Författare :Samuel Hammarberg; Pär Jonsén; Daniel Berglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight; Sandwich; Steel; Energy absorption; Homogenization; Finite element; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Lightweight materials and structures are essential building blocks for a future with sustainable transportation and automotive industries. Incorporating lightweight materials and structures in today's vehicles, reduces weight and energy consumption while maintaining, or even improving, necessary mechanical properties and behaviors.
