6. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications
University essay from Linköpings universitet/Mekanik och hållfasthetsläraAbstract : In the transition from conventional to green energy production resources, steam turbines are used to satisfy the lack of energy during peaks in the demand times and the limited access of renewable resources. This type of usage for steam turbines makes them operate on a flexible schedule, which leads to unpredictable issues related to shorter component life and faster crack propagation. READ MORE

7. Analysis of Barreling and Tolerance Effects of Blade Attachments
University essay from KTH/Hållfasthetslära (Avd.)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. READ MORE

8. Software Benchmark and Material Selection in an Exhaust Manifold : Thermo-mechanical fatigue simulation of an exhaust manifold in AVL Fire M
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : Today, there is a great focus on downsizing the engines, this means that the engines are made smaller in size but retain the same power. This in combination with the drive to increase the power of the engines has led to the engine components being exposed to high thermal loads. Today’s engines also use very high cylinder pressure.

9. Low Cycle Fatigue Weld Optimization using Chaboche Material Model
University essay from KTH/Hållfasthetslära (Avd.)Abstract : In this master thesis a method for optimizing welds has been investigated. The method was developed by the use of a finite element (FE)-model of a silencer. The silencer is exposed to both dynamic and thermal loads. Focus has been on using topology optimization for the welds. READ MORE

10. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure
University essay from Lunds universitet/MekanikAbstract : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. READ MORE
