1. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications
Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

2. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails
Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components.

4. Combined thermal and mechanical loading of railway wheel treads. A numerical study of material response and cracking under braking conditions
Abstract : The scope of the thesis is prediction of the material response owing to combined thermal and mechanical loading of a railway wheel tread. The long-term objective is to improve models for prediction of surface-initiated Rolling Contact Fatigue (RCF) under the combined effect of mechanical loading due to rolling (and sliding) contact and thermal loading due to braking and/or wheel--rail friction.

5. Mechanical braking systems for trains: A study of temperatures, fatigue and wear by experiments and simulations
Abstract : Increased demand for shorter travel times, higher axle loads, increased volumes and increased punctuality of railway traffic calls for a better design and management of the railway subsystems. The present thesis deals with aspects of mechanical friction brakes, in the form of tread brakes and disc brakes. READ MORE
