  1. 1. High strength steel local buckling and residual stresses

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mattias Clarin; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : High strength steel provide designers with the possibility of creating more slender and weight efficient structures than would be possible if using steels with lower strength. To be able to do this, a structural designer needs updated and validated codes as aid in their work. READ MORE

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anders Olsson; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    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

  3. 3. Structural steel plasticity : experimental study and theoretical modelling

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jan Granlund; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Abstract : Föreliggande avhandling behandlar konstitutiv modellering av konstruktionsstål i elastoplastiskt område. Ett koncept för tvåaxlig provning i huvudspänningsplanet har utvecklats vilket sedan har använts för att generera försöksdata för att formulera en konstitutiv modell för sambandet mellan spänningar och plastiska töjningar.

  4. 4. A study of slag-steel-inclusion interaction during Ladle treatment

    University dissertation from Stockholm : KTH

    Author : Johan Björklund; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ladle treatment; steel; slag; inclusions; ladle; refining; vacuum; tool steel; oxide activity; slag models; oxygen; equilibrium; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik;

    Abstract : The thesis is based on two supplements with two major objectives. In the first supplement equilibrium top slag-steel bulk and inclusions-steel bulk were investigated by comparison between calculated and measured oxygen activity values. This was done by applying different oxide activity models for slags combined with thermodynamic calculations. READ MORE

  5. 5. Environmental preferences among steel stakeholders

    University dissertation from Kalmar : Linnaeus University Press

    Author : Stina Alriksson; Linnéuniversitetet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conjoint analysis; environmental communication; focus group; light weighting; PLS; preferences; Q-methodology; risk perception; steel; stakeholders; Miljövetenskap; Environmental Science;

    Abstract : Emissions of carbon dioxide, dioxins, nitrogen oxides and particulate matter as well as use of non-renewable resources and energy are some important sustainability challenges for the Swedish steel industry. Much effort has been made, mainly by technical solutions, which to a high degree have decreased the emissions during the last 30 years. READ MORE
