16. Experiments, Computations and Models for Probabilistic HCF Design
Sammanfattning : High Cycle Fatigue (HCF) failure is a common failure type for many mechanical components. Traditional HCF design is based on the deterministic safety factor approach, typically used in conjunction with the point stress method. LÄS MER
17. Validation of models for welding and post weld heat treatment in product development of aerospace components
Sammanfattning : It is important to control key dimensions in aero engine components during manufacture. This is achieved by finding a stable process-parameter window for each manufacturing operation and to choose an order of manufacture, which gives an adequate result. Production planning has traditionally been carried out from experience and experiments. LÄS MER
18. Rolling Contact Fatigue of Railway Rails with Emphasis on Crack Initiation
Sammanfattning : Increased traffic density and the heavier axle loads of modern trains have led to severe problems with rolling contact fatigue (RCF) which cause initiation of surface cracks in railheads. In this thesis, a specific type of surface crack, the head check, is studied numerically with emphasis on fatigue crack initiation. LÄS MER
19. Behavioral and Electrophysiological Correlates of Inhibition in Episodic Memory
Sammanfattning : Forgetting can be highly functional when unwanted or irrelevant memory representations interfere with cognitive or motivational goals. Current theory assumes that forgetting can be brought about by the intentional or unintentional inhibition of interfering memory representations. LÄS MER
20. Dynamic analysis of a novel electromagnetic transducer for hybrid vehicle and experimental verification
Sammanfattning : This thesis presents the results of the work carried out on the dynamic analysis and experimental performance measurements of a novel concept of electromagnetic system for hybrid vehicle powertrains. The main focus of this work is to present how this novel electromagnetic system can be operated in a hybrid vehicle and to show how a prototype of this system has succesfully been operated in a laboratory set-up.
