  1. 6. Anisotropic mechanical behaviors and microstructural evolution of thin-walled additively manufactured metals

    Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Joe Kelleher; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot tensile testing; slow strain rate tensile testing; creep; anisotropy; crystallographic texture evolution; deformation twinning; Varmdragprov; Dragprov med låg töjningshastighet; kryp; anisotropi; kristallografisk textur; deformationstvillingar;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.

  3. 7. Structure and properties of Vasa oak

    Författare :Jonas Ljungdahl; Lars Berglund; Magnus Burman; Per Hoffmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oak; archaeological wood; European oak; transverse anisotropy; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The Vasa ship is not adequately supported. Measurements of the hull show that the ship deforms and rotate towards the port side. In addition, damages on the hull at support areas have been observed. The damages are due to high compressive loads. LÄS MER

  4. 8. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales

    Författare :Carl S. Modén; Lars Berglund; Per Johan Gustafsson; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära; Engineering mechanics; Teknisk mekanik; Biomaterials; Biomaterial;

    Sammanfattning : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. LÄS MER

  5. 9. Characterization of elastic moduli of single fibres

    Författare :Shanghong Duan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFM; Nanoindentation; Shear modulus; Transverse modulus; Carbon fibre;

    Sammanfattning : The carbon fibre is one of most promising materials for high-performance composites since it is lightweight and strong. It has been widely used to build carbon fibre reinforced polymer (CFRP) composites. The carbon fibre dramatically reinforces the composite in the fibre direction. LÄS MER

  7. 10. Microstructure Evolution and Mechanical Properties of Haynes 282

    Författare :Ceena Joseph; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma prime; carbide stabilization treatment; heat treatment; Haynes 282; isothermal transformation; anisotropy ductility; solution treatment; carbides; microstructure;

    Sammanfattning : Precipitation-hardened nickel-based superalloys find wide applications in aero engines and land-based gas turbines due to a combination of properties such as high temperature strength, resistance to oxidation and corrosion, fabricability, and creep strength. Structural engine components are traditionally cast to achieve higher degree of geometrical design freedom. LÄS MER
