  1. 1. Modelling and simulation of metal working processes

    Författare :Annika Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis consists of seven papers. All deal with the modelling and simulation of metal working processes. The aim of the research has been to increase understanding of this kind of process by studying specific problems and making models. The processes that have been studied are hot rolling, bending and ironing. LÄS MER

  3. 2. Processing and properties of glass mat thermoplastics

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

    Sammanfattning : The rapid processing of glass mat thermoplastics (GMT) is well known, large complex parts can be processed in less than one minute. It is however important that the material is produced properly to avoid a reduction in mechanical properties. There are some underlying industrial questions for this work. LÄS MER

  4. 3. Att tilltro sin handlingskraft : ett mentorprograms betydelse för fjorton kvinnors chefskarriärer

    Författare :Leif Nilsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pedagogik; Education;

    Sammanfattning : I avhandlingen studeras vilken betydelse ett mentorprogram har för fjorton kvinnors chefskarriärer. Lärandet i mentorprogrammet analyseras utifrån begreppet self-efficacy (handlingskraft), som innebär att tilltron till den egna kapaciteten att hantera en specifik arbetsuppgift utgör fundamentet för att välja en viss karriärväg.

  5. 4. Five essays on forest raw materials use in an international perspective

    Författare :Mats Nilsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : This dissertation consists of an introduction and five self-contained studies analyzing different aspects of roundwood markets. Geographically it is focused on Sweden (paper 1-3) and Russia (paper 4-5). Four of the papers (1-2, 4-5) are explicitly considering international trade and its effects and possibilities in the domestic markets. LÄS MER

  7. 5. Thermal cracking of young concrete : partial coefficients, restraint effects and influence of casting joints

    Författare :Martin Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Cracks can occur due to temperature induced movements during the hardening phase of concrete. Thermal cracks are not decisive for the load-bearing capacity but cause costs for repair and may reduce the life of the structure. The risk of cracking can be judged through safety values, (partial coefficients) given in building codes. LÄS MER
