  1. 1. Fatigue life prediction of additively manufactured ductile nickel-based superalloys : Constitutive and crack initiation modelling

    Författare :Thomas Lindström; Daniel Leidermark; Kjell Simonsson; Robert Eriksson; Magnus Ekh; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Low-cycle fatigue; Thermomechanical fatigue; Constitutive modelling; Anisotropy;

    Sammanfattning : This dissertation was produced at the Division of Solid Mechanics at Linköping University, and is the final result of a project that included mechanical testing and modelling of an additively manufactured ductile nickel-based superalloy.The main objective of the work presented in this thesis was to investigate and model the cyclic behaviour and the fatigue life behaviour of an additively manufactured ductile nickel-based superalloy, with emphasis on modelling the stabilised material behaviour, by which fatigue life predictions can be based upon.

  3. 2. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution

    Författare :Anders Petersson; KTH; []
    Nyckelord :Cemented carbides; Sintering; Constitutive relations; Microstructure; Densification; Modelling;

    Sammanfattning : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. LÄS MER

  4. 3. 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

  5. 4. The School as a Moral Arena : Constitutive values and deliberation in Swedish curriculum practice

    Författare :Katarina Norberg; David Hamilton; Pirjo Lahdenperä; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; Constitutive values; curriculum; moral; schooling; intercultural education; multicultural school; Pedagogik; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : This thesis’ main theme is the relation between school practices and the constitutive values explicitly endorsed in the Swedish national curriculum. It consists of four articles. Article I examines the new educational circumstances in a multicultural society. LÄS MER

  7. 5. Making Accounting Matter : A Study of the Constitutive Practices of Accounting Framers

    Författare :Charlotta Bay; Bino Catasús; Gustav Johed; Yves Gendron; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; constitutive role; interpretation; accounting framer; private sphere; identification design practices; representation; social construction; Business Studies; Företagsekonomi;

    Sammanfattning : The idea of accounting as a constitutive means, making people think and act in particular ways, is well established in the social strand of accounting literature. In professional organisations, for example, accounting is claimed to be critical to processes of turning people into rational and responsible economic actors. LÄS MER
