16. Damage and defects in railway materials: influence of mechanical and thermal damage on crack initiation and propagation
Sammanfattning : With rising societal concern for the environment, railways offer travelers a sustainable alternative to other forms of fossil-fueled transportation. In order to be competitive with airlines, for example, the railway industry must provide safe, efficient, and affordable service. LÄS MER
17. Guided wave-based approach for health monitoring of composite structures; Application to wind turbine blades
Sammanfattning : The use of composite materials has increased in manufacturing of large structures. These structures can be subjected to different types of defects, for which detection has always been a challenge. LÄS MER
18. Challenges in aero engine performance modeling
Sammanfattning : There is a continuous drive for ever more efficient aero engines due to environmental as well as economical concerns. As the technology of conventional turbofan engines matures, there is a need for new aero engine concepts as well as incremental improvement of existing technologies. LÄS MER
19. Crack growth in single crystal nickel base superalloys under isothermal and thermomechanical fatigue
Sammanfattning : This work concerns the fatigue crack growth behaviour of nickel base single crystal superalloys. The main industrial application of this class of materials is in gas turbine blades, where the ability to withstand severe mechanical loading in combination with high temperatures is required.

20. Transient Spray Mode Fuel Injection
Sammanfattning : This research examines the pivotal role of transient fuel spray in internal combustion engines, primarily focusing on their influence on dual-fuel (DF) engines. In the case of dual-fuel (DF) engines functioning in a gas mode, the controlling of the primary fuel’s ignition is usually managed through the direct injection of liquid pilot fuel. LÄS MER
