  1. 16. Mechanics of composites with fiber bundle meso-structure

    Författare :Normunds Jekabsons; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The presented thesis analyze mechanical phenomena in fibrous composites with fiber bundle sub-structure (woven composite sheet molding compounds (SMC) etc.). This sub-structure defines an intermediate meso-scale between the scale of individual fibers and macro-scale of the composite. LÄS MER

  3. 17. Some Basic Problems in Rock Breakage by Blasting and by Indentation

    Författare :S.Q. Kou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : This thesis is devoted to discussing some basic problems in rock breakage by blasting and by mechanical excavation, and contains a detailed summary and six appended papers numbered as Papers A to F. The central problem treated in this thesis is the interaction between either explosion products or mechanical tools and rock. LÄS MER

  4. 18. Fatigue Assessment of Friction Stir Welded Joints in Aluminium Profiles

    Författare :Meysam Mahdavi Shahri; Rolf Sandström; Per Jahn Haagensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Fatigue; Aluminium alloys; Critical distance; Finite element method; Standard codes;

    Sammanfattning : Friction stir welding (FSW) is a low heat input solid state welding technology. It is often used for fabrication of aluminium alloys in transportation applications including railway, shipbuilding, bridge structures and automotive components. LÄS MER

  5. 19. X-Ray Diagnostics in Combustion - Study of Particle Formation in Flames Using Combined Small- and Wide-Angle X-Ray Scattering

    Författare :Linda Vallenhag; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; soot particles; WAXS; X-ray scattering; SAXS; combustion; Fysicumarkivet A:2014:Vallenhag;

    Sammanfattning : In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtained.

  7. 20. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Författare :Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Sammanfattning : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. LÄS MER
