  2. 2. On an Efficient Method fo Time-Domain Computational Aeroelasticity

    Författare :David Eller; Ulf Ringertz; Paolo Mantegazza; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroelasticity; unsteady aerodynamics; boundary element method; multidisciplinary simulation; Vehicle engineering; Farkostteknik;

    Sammanfattning : The present thesis summarizes work on developing a method for unsteady aerodynamic analysis primarily for aeroelastic simulations. In contrast to widely used prediction tools based on frequency-domain representations, the current approach aims to provide a time-domain simulation capability which can be readily integrated with possibly nonlinear structural and control system models.

  3. 3. Generalised stacking fault energy and plastic deformation of austenitic stainless steels

    Författare :David Molnar; Levente Vitos; Guocai Chai; Dávid Sándor Molnár; Högskolan Dalarna; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; stacking fault energy; stainless steel; plasticity; deformation; ab initio; Steel Forming and Surface Engineering; Stålformning och ytteknik; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Austenitic stainless steels are primarily known for their exceptional corrosion resistance. They have the face centred cubic (FCC) structure which is stabilised by adding nickel to the Fe-Cr alloy. The Fe-Cr-Ni system can be further extended by adding other elements such as Mn, Mo, N, C, etc. in order to improve the properties. LÄS MER

  4. 4. Stacking fault energy and deformation behaviour of austenitic stainless steels: a joint theoretical-experimental study

    Författare :Dávid Sándor Molnár; Levente Vitos; Göran Engberg; Guocai Chai; David Molnar; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation properties; stacking fault energy; electron backscatter diffraction; ab initio; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Sammanfattning : Austenitiska rostfria stål är främst kända för sin exceptionella korrosionsbeständighet. De har en ytcentrerad kubisk (FCC) struktur som stabiliseras genom att nickel, mangan eller kväve tillsätts till Fe-Cr legeringen. Fe-Cr-Ni-systemet kan utökas ytterligare genom tillsats av andra element såsom Mo, Cu, Ti, C, etc. LÄS MER

  5. 5. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water

    Författare :Anna Andersson; David Bastviken; Henrik Kylin; David Reckhow; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Water treatment technologies; chemical disinfection; FT-ICR MS; bioassays; Vattenreningstekniker; klor; kloramin; FT-ICR MS; effektbaserad analys;

    Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER
