  2. 6. The influence of graphite morphology on the elastic behaviour of cast irons

    Author : Torsten Sjögren; Linköpings universitet; []
    Keywords : Cast iron; flake graphite; compacted graphite; spheroidal graphite; elastic behaviour; modulus of elasticity; graphite modulus of elasticity; nodularity; aspect ratio; plastic deformation; acoustic emission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The morphology of the graphite phase largely controls the resulting properties of different grades of cast iron. In flake graphite cast irons, the mechanical properties are low while the thermal conductivity is high. In contrast, with spheroidal graphite cast irons, the mechanical properties are high while the thermal conductivity is low. READ MORE

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

    Author : Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 8. High Performance Manufacturing of Advanced Thin Plates ─ Forming of Titanium and Stainless Steel Materials

    Author : Per Gabrielson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High performance manufacturing; test tools; sheet-metal forming; stainless steel; commercially pure titanium; process optimization; forming simulation; finite element analyses; acoustic emission; production performance analysis; cost models; manufacturing costs; sustainable production;

    Abstract : The manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. READ MORE

  6. 9. Particulate Emissions Associated with Diesel Engine Oil Consumption

    Author : Petter Tornehed; Ulf Olofsson; Gordon E. Andrews; KTH; []
    Keywords : Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; Mechanical engineering; Maskinteknik;

    Abstract : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. READ MORE

  7. 10. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

    Author : Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.
