  2. 6. Stainless steel plasticity : material modelling and structural applications

    Author : Anders Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. READ MORE

  4. 7. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails

    Author : Dimitrios Nikas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low cycle fatigue LCF ; Wheel steels; Hardness; TEM; Thermal effects; EBSD; Rail steels; Pearlite; Multiaxial fatigue; Spheroidisation; Materials Science;

    Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components.

  5. 8. Resin transfer moulded composite materials : processing, structure, property relationships

    Author : J. Anders Holmberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.
