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

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Ahmed Azeez; [2018]
   Keywords : ;

   Abstract : 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

3. 17. Influence of Nitrocarburization on Thermo-Mechanical Fatigue Properties : Material Characterization of Ductile Cast Iron for Exhaust Components

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Wännman Sofia; [2018]
   Keywords : Ductile cast iron; Nitrocarburizing; Thermo-mechanical fatigue;

   Abstract : The large number of vehicles operating on the roads cause high emissions and consequently a negative effect on the environment. When developing and optimizing internal combustion engines, certain requirements must be considered, which are environmental regulations, reduced fuel consumption and increased specific power.

4. 18. Fretting tests on connector terminals

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Marcus Magnusson; [2018]
   Keywords : Fretting; Corrosion; Laser vibrometry; Connector; Vibration; Technology and Engineering;

   Abstract : Fretting is a complex set of mechanical and electrical mechanics that occurs at the contact surface between two vibrating objects. It is widely present in electrical connectors close to combustion engines due to the constant exposure to vibrations. Fretting is an extensive problem in the automotive industry but little research is done. READ MORE
