  1. 1. A Framework for Fatigue Analysis of Carbon Fiber Reinforced Polymer Structures

    Författare :Sara Eliasson; Zuheir Barsoum; Per Wennhage; Kim Branner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy-duty vehicles; Fatigue; Carbon fiber reinforced polymer; Multi-scale modeling; Probabilistic modeling; Tunga fordon; Utmattning; Kolfiberkomposit; Probabilistisk modellering; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : Our society depends on functional road communication, and Heavy Duty Vehicles (HDVs) offer convenient and limitless possibilities of transport and services. However, HDVs account for a quarter of the European Union's CO2 road emissions. There is a substantial need to reduce the CO2 emissions of HDVs to ensure a low negative environmental impact. LÄS MER

    Sammanfattning : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. LÄS MER

  4. 3. Modelling and numerical analysis of leakage through metal-to-metal seals

    Författare :Francesc Pérez Ràfols; Vladislav Yastrebov; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Metal-to-metal seals are critical components as their failure can lead to leakage of hazardous fluids to the environment or to fatal failure of the systems they operate on. Most systems are subjected to increasingly more demanding conditions and deeper knowledge about how different parameters affect the leakage is necessary to design seals with the desired performance.
