  1. 11. Modelling of the Fletcher-Gent effect and obtaining hyperelastic parameters for filled elastomers

    Författare :Rickard Österlöf; Leif Kari; Per-Erik Austrell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; filled elastomers; natural rubber; carbon black; Fletcher-Gent effect; Payne-effect; finite strain; hyperelastic;

    Sammanfattning : The strain amplitude dependency , i.e. the Fletcher-Gent effect and Payne effect, and the strain rate dependency of rubber with reinforcing fillers is modelled using a modified boundary surface model and implemented uniaxially. LÄS MER

  3. 12. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface

    Författare :Mattias Bäckström; Gunnar Jacks; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lead; trace elements; traffic; shooting range; peat; sediments; speciation; biokemi; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. LÄS MER

  4. 13. Heavy truck modeling for fuel consumption simulations and measurements

    Författare :Tony Sandberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Fuel consumption for heavy trucks depends on many factors like roads, weather, and driver behavior that are hard for a manufacturer to influence. However, one design possibility is the powertrain configuration. LÄS MER

  5. 14. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials

    Författare :Simon Magnusson; Sven Knutsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER

  7. 15. Assessing and modelling impact sound insulation of wooden joist constructions

    Författare :Wanqing Shi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Sammanfattning : Impact sound insulation is one of the most important aspects when assessing sound insulation of floor constructions in buildings. For assessing the impact sound insulation of aconstruction, a standard tapping machine is used as a sound source. LÄS MER
