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

    Detta är en avhandling från Luleå : Luleå tekniska universitet

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

    Sammanfattning : 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. LÄS MER

  2. 2. Residual stresses in dental composites

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Philippe Lingois; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : In several European countries, dental composites are replacing mercury-containing amalgams as the most common restorative materials. The problems with dental composites are they can induce pain for the patient, fracture of the tooth, gap between the tooth and the filling what will induce secondary caries. The main reason is residual stresses. LÄS MER

  3. 3. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Mohsen Sadrossadat; Linköpings universitet.; Linköpings universitet.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si alloys; residual stresses; microstructure; microsegregation; nucleation behavior; modeling; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. LÄS MER

  4. 4. Residual Stress Analysis and Fatigue of Welded Structures

    Detta är en avhandling från Stockholm : Farkost och flyg

    Författare :Zuheir Barsoum; KTH.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; fatigue; finite element analysis; fracture mechanics; residual stresses; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik;

    Sammanfattning : This licentiate thesis is generally concerned with the fatigue of welded structures. Several topics related to fatigue of welded structures are treated such as; weld defects and their influence on fatigue performance of welded structures, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, welding simulation, residual stress prediction and measurement and their influence on fatigue.

  5. 5. Residual stresses in paperboard and the influence of drying conditions

    Detta är en avhandling från Stockholm : Hållfasthetslära

    Författare :Magnus Östlund; KTH.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper; drying; mechanical properties; residual stress; curl;

    Sammanfattning : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. LÄS MER
