1. Fatigue life extension in existing steel bridges. High-Frequency Mechanical Impact treatment and Tungsten Inert Gas remelting in life extension and fatigue crack repair of welded steel structures
Abstract : This thesis investigates the performance of improved welds with two post-weld treatment methods for application on existing structures. High-Frequency Mechanical Impact (HFMI) treatment and Tungsten Inert Gas (TIG) remelting were used for fatigue life extension of welded structures. READ MORE

2. The Influence of Residual Stresses on Fatigue Behaviour of Medium Carbon Microalloyed Steel
Abstract : Subjected to the dynamic loading, truck components are exposed to fatigue loading. Hence the methods to improve the fatigue properties of the components are widely employed by manufacturers. One of the well known methods in this field is shot peening. READ MORE

3. The Influence of Residual Stresses on Constant and Variable Amplitude Fatigue Behaviour of Steel
Abstract : Subjected to dynamic loading, truck components are exposed to variable amplitude fatigue. The fatigue life of components is to a large degree controlled by the behaviour of the surface zones. READ MORE

4. Life prediction and mechanisms for the initiation and growth of short cracks under fretting fatigue loading
Abstract : Fretting fatigue is a damage process that may arise in engineering applications where small cyclic relative displacements develop inside contacts leading to detrimental effects on the material fatigue properties. Fretting is located in regions not easily accessible, which makes it a dangerous phenomenon. READ MORE

5. Residual Stresses and Fatigue of Shot Peened Cast Iron
Abstract : The complex geometry of cylinder head in heavy-duty diesel engine makes grey cast iron or compact graphite iron a perfect material choice due to its castability, thermal conductivity and damping capacity. To increase the efficiency of the engine, the fatigue property of the material needs to be improved. READ MORE
