  2. 2. On initiation of chemically assisted crack growth and crack propagation paths of branching cracks in polycarbonate

    University dissertation from Ulf Hejman/Media-Tryck AB

    Author : Ulf Hejman; Lunds universitet.; Lund University.; Malmö University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stress corrosion; crack initiation; multiple cracking; polycarbonate; three point bending; branching.; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys; TECHNOLOGY Engineering mechanics Solid mechanics; TEKNIKVETENSKAP Teknisk mekanik Fastkroppsmekanik; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; Sciences; stress corrosion cracking; dissolution; branching; experiment; finite element modelling;

    Abstract : Stress corrosion, SC, in some cases gives rise to stress corrosion cracking, SCC, which differs from purely stress intensity driven cracks in many aspects. They initiate and grow under the influence of an aggressive environment in a stressed substrate. They grow at low load and may branch. READ MORE

  4. 4. On Surface Topography of Cylinder Liners

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Zlate Dimkovski; Högskolan i Halmstad.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation;

    Abstract : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  5. 5. Surfaces of Honed Cylinder Liners

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Zlate Dimkovski; Högskolan i Halmstad.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science Surface engineering; TEKNIKVETENSKAP Teknisk materialvetenskap Ytbehandlingsteknik; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation;

    Abstract : Cylinder liner surfaces are often on the agenda of engine developers because of their large influence on the frictional losses, oil consumption and emissions of internal combustion engines. Improving the liner function involves not only manufacturing new surfaces and checking their function but also characterising them as a necessary intermediate step for better understanding of the changes made.
