  1. 1. Numerical simulations of wear

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mona Öqvist; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The objective of this licentiate thesis was to study the effect of tool wear for sheet metal forming tools and how the wear process can be simulated in an efficient manner. Three Papers are appended to this licentiate thesis. Paper A covers the influence of tool geometry in deep drawing. READ MORE

  2. 2. Thermal response test numerical simulations and analyses

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Anna-Maria Gustafsson; Luleå tekniska universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Abstract : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. READ MORE

  3. 3. Strength and Moisture Aspects of Steel Timber Dowel Joints in Glulam Structures An Experimental and Numerical Study

    University dissertation from Växjö : Växjö University Press

    Author : Johan Sjödin; Växjö universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constraint stresses; contact-free measurement; dowel-type joints; humidity variations; glu-lam beams; glulam structures; linear elastic fracture mechanics; moisture-induced stresses; numerical simulations; short term capacity.; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : Joints are critical parts of timber structures, transmitting static and dynamic forces between structural members. The ultimate behavior of e.g. a building depends strongly on the structural configuration and the capacity of its joints. READ MORE

    Abstract : Popular Abstract in Swedish I utvecklingen av gasturbiner och förbränningsmotorer (som används i bilar, flygplan & båtar) finns idag ett modernt miljötänkande som strävar efter att reducera utsläpp och öka effektiviteten (verkningsgraden). Med användning av rätt kylmetoder kan man påverka dessa parametrar. READ MORE

  5. 5. Numerical Simulations of Plasmonic Nanostructures

    University dissertation from Mrs Gunvi Andersson, Div. Heat Transfer, Box 118, 22100 Lund, Sweden

    Author : Joan Alegret; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoholes; DDA; Green s tensor; nanostructures; surface plasmons;

    Abstract : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. READ MORE
