  1. 21. Patch loading resistance of welded I-beams : with respect to misaligned web stiffeners

    Master-uppsats, KTH/Stålbyggnad

    Författare :John-Alexander Boutzas; Dafina Zeka; [2016]
    Nyckelord :Patch loading; Stiffeners; I-beam; Plated steel structures; Abaqus; Simply supported beam;

    Sammanfattning : When a concentrated load is introduced perpendicular to the flanges of a steel beam, this condition is referred to as Patch loading (Gozzi, 2007). This occurrence is common in many steel structures, for example at supports or during launching of bridges. LÄS MER

  3. 22. Numerical and experimental study of embossing of paperboard : A material characterization of one specific paperboard quality

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Lisa Runesson; [2016]
    Nyckelord :Embossing; Paperboard; Abaqus; FEM; Creasing;

    Sammanfattning : This master thesis has its main focus within embossing operations and how different factors influence the result. The work was performed at Stora Enso Research Centre in Karlstad, Sweden. Embossing is relatively complex operation to analyze since the paperboard can be exposed of both bending, shear and compression at the same time. LÄS MER

  4. 23. Förutsättningar för ökad metervikt och axellast på Malmbanan

    Master-uppsats, KTH/Transportplanering, ekonomi och teknik

    Författare :Anton Dahlberg; Ludvig Jangenstål; [2016]
    Nyckelord :;

    Sammanfattning : LKAB intends to increase the production of iron ore in the upcoming years. To prevent problems with the capacity along Malmbanan (The Iron Ore Line) an increase in the maximum permissible axle load is required. The first step is an increase from 30 ton to 32.5 ton. LÄS MER

  5. 24. Difficulties in FE-modelling of an I-beam subjected to torsion, shear and bending.

    Master-uppsats, KTH/Byggvetenskap

    Författare :Miriam Alexandrou; [2015]
    Nyckelord :Difficulties; FE-modelling; I-beam; shear; torsion; bending; ABAQUS;

    Sammanfattning : In this thesis six different models of IPE240 have been created in order to study their behavior undershear, bending and torsion. These models simulate IPE240 but differ in the boundary conditions, inthe loading and the length of the beam and in some connections which connect certain elements. LÄS MER

  7. 25. Framtagning av ny bärare för kassettöverdelar

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Johan Berglund; [2015]
    Nyckelord :Koncept; Produktframtagning; TRIZ;

    Sammanfattning : Fiomi Diagnostics AB manufactures and develops point of care cassettes for bloodsamples to determine risk of myocardial infarction and heart failure for use within thehealthcare sector. The cassette contains of three main parts; top, bottom and a plasticchip. LÄS MER
