1. 1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

   University essay from KTH/Hållfasthetslära

   Author : Alfred Norberg; [2023]
   Keywords : Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

   Abstract : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. READ MORE

3. 2. 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

4. 3. 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

5. 4. Evaluation of Ground Anchor for Temporary Shelters : - Performance, Design and Alternative Materials

   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

6. 5. 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.
