  1. 1. Transformation of In-Flight Measured Loads to a Fatigue Test Spectrum

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Patrick Dümig; [2022]
    Keywords : Aerospace engineering; Aircraft load spectra; ASIP; Crack growth; Fatigue testing; Flight loads; Flight test; Fracture mechanics; FSFT; In-flight measurements; Load spectrum reduction; Racetrack filtering; Strain gauge measurements;

    Abstract : Fatigue is a well-recognized issue in lightweight and high-performance aircraft structures. As fatigue failures have led to serious accidents and caused significant economic impact in the past, design against fatigue is crucial. READ MORE

  2. 2. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Treitler; [2022]
    Keywords : Fatigue; Kaplan; Hydropower; Turbine;

    Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Patrik Ter Vehn; Viktor Olsson; [2018]
    Keywords : ;

    Abstract : Better Shelter is a company, developing and providing module housing units for refugees in crisis areas. These module housing units are kept in place against wind and harsh conditions by 10 ground anchors, that are buried and tied to the frame. READ MORE

  4. 4. Analysis of Barreling and Tolerance Effects of Blade Attachments

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Yuanyuan Xu; [2018]
    Keywords : ;

    Abstract : In a gas turbine rotor, the Blade-Disc attachment is often a critical part. This part needs to endure both high contact stress and high temperature. Thus, the prediction of the life of the attachment becomes important.  Furthermore, the refinement of the Blade-Disc attachment is worth to study, to extend the lifetime of the turbine rotor.

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

    University essay from KTH/Bro- och stålbyggnad

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

    Abstract : 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. READ MORE
