1. 21. Fatigue Life Analysis of Weld Ends : Using FE-Calculations and Mechanical Testing

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Victor Ljungdahl; [2018]
   Keywords : Comparison; Effective notch method; Testing; Weld End; Jämförelse; Effective notch metoden; Provning; Svetslut;

   Abstract : Fatigue life estimation of welds is a complex issue since the characteristics of each weld are unique depending on load case, geometry and properties. Fatigue life estimation on weld ends is limited and often the weakest point of a weld. READ MORE

3. 22. Thermal cracking of a concrete arch dam due to seasonal temperature variations

   University essay from KTH/Betongbyggnad

   Author : Jonas Enzell; Markus Tollsten; [2017]
   Keywords : Arch dam; Concrete; Finite element analysis; Cracking; Progressive failure analysis; Valvdamm; Betong; Finit elementanalys; Sprickor; Progressiv brottanalys;

   Abstract : Concrete dams located in northern regions are exposed to large seasonal temperature variations. These seasonal temperature variations have resulted in cracking in thin concrete dams. Continuous monitoring and evaluation of existing dams are important to increase the knowledge about massive concrete structures and to ensure dam safety. READ MORE

4. 23. 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

5. 24. Numerical analyses of concrete buttress dams to design dam monitoring

   University essay from KTH/Betongbyggnad

   Author : Daniel Svensen; [2016]
   Keywords : Concrete; buttress dams; thermal effects; finite element analysis; instrumentation; alarm values; alert values; Betong; lamelldammar; termiska effekter; finit element analys; intstrumentering; larmvärden;

   Abstract : Old concrete buttress dams are sensitive to cracking if exposed to large temperature variations. The cracks can make dams sensitive to failure, depending on the size and location of the cracks. These problems can be overcome by lowering the temperature variations and stabilizing the dams.

6. 25. Reliability prediction of electronic products combining models, lab testing and field data analysis

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Noor Choudhury; [2016]
   Keywords : Reliability; Reliability Standards; Benchmark; Field data analysis; Thermal Cycling test; FIDES; Siemens SN 29500; IEC 62380; MIL-HDBK-217F-Notice2; Reliability Prediction; Accelerated Life Test; Product Reliability; Pålitlighet; Tillförlitlighetsstandarder; Riktmärke; Fältdatanalys; Termisk cykelstest; FIDES; Siemens SN 29500; IEC 62380; MIL-HDBK-217F-Notice2; tillförlitlighet förutsägelse; accelererade livslängdstestet; Produktens tillförlitlighet;

   Abstract : At present there are different reliability standards that are being used for carrying out reliability prediction. They take into consideration different factors, environments and data sources to give reliability data for a wide range of electronic components. READ MORE
