  1. 1. Cracking and Fatigue in the Prestressed Concrete Bridge at Autio

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Andersson; Jon Leidzén; [2022]
    Nyckelord :Fatigue; Cracking; Prestressed Concrete Bridge; Rainflow;

    Sammanfattning : In early 2020, cracks were discovered on the bridge crossing the Torne River at Autio. This resulted in an investigation being launched to determine the structural state of the bridge. LÄS MER

  3. 2. Continuous Time Fatigue Modelling for Non-proportional Loading

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sajjan Gundmi Satish; [2019]
    Nyckelord :Multiaxial Fatigue Loading; Fatigue Analysis; Continuous Time fatigue model; Endurance Surface; Rainflow Counting; Cyclic loading; Cycle Counting; Damage Evolution; High-cycle fatigue; Non-proportional loading;

    Sammanfattning : Fatigue analysis is a critical stage in the design of any structural component. Typically fatigue is analysed during post-processing, but as the size of the analysed component increases, the amount of data stored for the analysis increases simultaneously. LÄS MER

  4. 3. Development of Tool in MATLAB for the Durability Prediction of Radiators

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Akhil Mora; Raghavendra Machipeddi; [2017]
    Nyckelord :Basquin’s coeffcient; Cycle counting; Level Crossing; Thermal Cycling; Wöhler curve.;

    Sammanfattning : Durability is the most important factor in the design of heat-exchangers to meet the specifications of the customers. To predict the durability, endurance tests are carried out. In this thesis, one of the endurance tests, thermal cycling is performed for three different internal coolant flows until failure which is known as Wöhler test. LÄS MER

  5. 4. Fatigue Analysis of Mooring Lines in Floating Bridges : Influence of Line Configuration and Water Depth in a Case Study in Bjørnafjorden

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Borja Balbastre Camarena; [2017]
    Nyckelord :Floating bridge; E39 project; Fatigue Damage Evaluation; Mooring Lines; Pontoon; ANSYS.;

    Sammanfattning : Nowadays, the Norwegian Public Roads Administration plans to replace the ferry connections along the western coast of Norway with fixed road connections through the coastal highway E39 project. Due to the necessity of bridging long distances with considerable depths, non-conventional engineering solutions are being developed. LÄS MER

  7. 5. Lifetime Monitoring of Wind Turbines

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Lars Nilsson; [2005]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The aim of this thesis was to design and implement a lifetime monitoring system for a GE Energy wind turbine. Monitoring the loads on the main components of a wind turbine makes it possible to keep the lifetime of the components monitored. This information can be used to enable more flexible planning of a wind turbine's maintenance. LÄS MER
