  1. 16. Reduced stress method for steel in class 4 cross-sections : Evaluation of the reduced stress method for a railway bridge

    University essay from KTH/Byggteknik och design

    Author : Therese Badrous; Ebba Lund; [2021]
    Keywords : FEM; Reduced stress method; Effective cross-section method; Local buckling; Steel cross-section; Class 4 cross-section; Railway bridge; FEM; Reducerad spänningsmetoden; Effektivt tvärsnittsmetoden; Lokal buckling; Ståltvärsnitt; Tvärsnittklass 4; Järnvägsbro;

    Abstract : The effective cross-section method, also called reduced cross-section method is generally used for steel in class 4 cross-sections in considering local buckling. This method is a bit complicated and time consuming, which often leads to engineers not using profiles in class 4 cross-sections. READ MORE

  3. 17. Expansion Joints in timber bridges : Mechanical behavior under external loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Johan Gustafsson; Jakob Myhrberg; [2021]
    Keywords : Expansion joint; FE-modeling; Timber bridges; Steel-to-wood connections; European Technical Approval Guidelines;

    Abstract : To design a bridge, different typologies of construction materials can be used. All materials have in common that deformations occur due to different events, such as externalloading, temperature- and moisture variations. To allow these kinds of deformations,Expansion Joints (EJs) are used in the structure. READ MORE

  4. 18. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Niclas Elfving; Joel Sunesson; [2021]
    Keywords : Concrete; Creep; Segmentally constructed; Prestressing; Post-tensioning; Viscoelastic; Eurocode; Finite Element; Shell elements; Beam elements; Time-dependant; Steel relaxation.; Technology and Engineering;

    Abstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE

  5. 19. Fretting fatigue life analysis for a gas turbine compressor blade-disk material combination

    University essay from KTH/Hållfasthetslära

    Author : Elham Khoramzad; [2020]
    Keywords : ;

    Abstract : In order to analyse fretting fatigue life of dove-tail joints used in the compressor stage of a gas turbine, experimental study of different material combinations was conducted using rectangular fatigue specimen and bridge type pads. Specimen and pad interaction was simulated numerically and obtained results was used as input for 2 different crack propagation life prediction methods. READ MORE

  6. 20. Cost-effective manufacturing process for plastic components in automotive industry

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Gustav Bergling; Vishnu Nair; [2020]
    Keywords : manufacturing processes; plastic components; automotive industry;

    Abstract : A seemingly increasing trend in the automotive industry is the prevalence of hybrid and electric vehicles. For Lear Corporation, a global automotive supplier of seating and electronic systems, this has caused a decrease in quantity of their products as these types of vehicles are manufactured at lower rates of volumes.
