  1. 1. Fatigue strength assessment of post weld improved welded joints

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Veronika Nerbe; [2023]
    Keywords : Mechanics; solid mechanics; lightweight structures; hfmi; weld; Mekanik; hållfasthetslära; lättkonstruktioner; hfmi; svets;

    Abstract : In this thesis work a literature survey is done to collect published data for T-welded joints with a thickness of 5-12 mm, produced in high strength steel and treated with HFMI. In addition to this, large structures are researched. READ MORE

  3. 2. EVALUATING HEAT TREATMENT AS A METHOD TO REDUCE BIOFOULING IN OYSTER AQUACULTURE. Heat tolerance in Swedish grown Magallana gigas and Ostrea edulis.

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Niklas Agblad; [2022-09-28]
    Keywords : ;

    Abstract : Aquaculture is a growing business in various parts of the world, Sweden included. As the commercial use of oysters increases, so does its demand. Farmers will need to produce a high quality product that is appealing to the customer and cost-effective for the farmer. READ MORE

  4. 3. Assessment of the Agroecological Potential of Biostimulatory Effects : originating from Effective Microorganisms (EM) in terms of Environmental and Socioeconomic Aspects

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Tania Schwarzer; [2022]
    Keywords : effective microorganisms; agroecology; biostimulants; beneficial microorganisms; lactic acid bacteria; bokashi; semi-structured interviews; interpretative phenomenological approach;

    Abstract : Environmental pollution, resource depletion and climate change are related to imbalances in the farming system. Effective microorganisms are seen as a possible solution to these problems. READ MORE

  5. 4. Strengthening of non-composite bridges by Partial Composite Action

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Johan Tjernberg; [2022]
    Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Abstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  6. 5. 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
