1. 1. Effect of dwell time on stress intensity factor of ferritic steel for steam turbine applications

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Ahmed Azeez; [2018]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

3. 2. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Ahmed Elschich; [2017]
   Nyckelord :Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

   Sammanfattning : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. LÄS MER
