1. 1. A Structural Analysis of the Fracture Sets in Gothenburg, Sweden: A Remote Sensing and Manual Lineament Approach

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Jacek Krysik; [2023-05-22]
   Keywords : Remote sensing; Manual lineament analysis; Fractal analysis; Structural; Regional geology; LiDAR; Gothenburg region;

   Abstract : The fracture-valley landscape within the Gothenburg region was analysed based on LiDAR-derived hillshade images as well as several sources of orthomosaics. Using a manual lineament interpretation approach and complimented with an objective fractal analysis software (FROST), the objective of the study was to characterise the regional fracture sets as well as attempt to link the sets to the complex regional geological history.

3. 2. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

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

   Author : Muhammad Hashir Zaheer; [2023]
   Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

   Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

4. 3. Impact of Residual Stress on the Warm Pre-Stressing Effect

   University essay from KTH/Hållfasthetslära

   Author : Emil Danielsson; [2023]
   Keywords : Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

   Abstract : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. READ MORE

5. 4. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

   University essay from KTH/Byggnadsmaterial

   Author : Charlotte Jaeger; [2023]
   Keywords : ;

   Abstract : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. READ MORE

6. 5. Precipitation analysis in bearing steel Hybrid 60

   University essay from KTH/Materialvetenskap

   Author : Rebecca Rosén; [2023]
   Keywords : martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

   Abstract : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. READ MORE
