  1. 1. Constitutive Behaviour and Fracture of Adhesive Layers : Inverse Methods and Energetic Balance

    Författare :Svante Alfredsson; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; constitutive behaviour; fracture; energy release rate; shear fracture; mode-mixity; experimental method; inverse solution; multi-material joints; TECHNOLOGY; TEKNIKVETENSKAP; Teknik; Technology;

    Sammanfattning : In the automobile industry, current demands on reduced emissions with maintained or even increased crash worthiness, forces the industry to seek weight-reducing designs. The possibility to use lightweight materials is obviously attractive. At joints, these lightweight materials have to be connected to high-strength or low-cost materials. LÄS MER

  3. 2. Delamination in APS applied thermal barrier coatings : life modelling

    Författare :Magnus Jinnestrand; Esteban Busso; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Thermal barrier coatings, TBCs, are used in gas turbines as a thermal shield resulting in lower temperature in coated components. The decrease of temperature allows higher gas temperatures in the turbine, which increase the efficiency. LÄS MER

  4. 3. Mechanical Behaviour of Single-Layer Adhesive Joints : an integrated approach

    Författare :Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; beam adhesive layer model; energy release rate; fracture; integrated; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : Innovative products that are competitive on the market are likely to employ newtypes of materials and unusual geometries. A method that can assemble dissimilarmaterials and irregular geometries cost-effectively and at the same time offera joint that is light in weight and imperceptible, is optimal. LÄS MER

  5. 4. Modelling and simulation of short fatigue cracks

    Författare :Christina Bjerkén; Materialteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Material technology; Interface cracks; Dislocations; Short cracks; Local plasticity;

    Sammanfattning : The growth of short fatigue cracks deviates from the behaviour of long fatigue cracks even if subjected to the same nominal driving force. The influence from the microstructure is pronounced, while crack closure effects may not be that important as for longer cracks. LÄS MER
