1. Railway wheel steel behaviour upon thermo-mechanical loadings
Abstract : Optimised railway maintenance techniques such as rail grinding and milling, or rail repair welding, are vital to more sustainable rail networks. As demands on the railway increases, the need to better understand the material behaviour during local heating events occurring during maintenance is amplified. READ MORE

2. Deformations and stresses in welded pipes : numerical and experimental investigation
Abstract : In this dissertation, deformations and stresses in welded pipes have been studied both numerically and experimentally. The aim of this work has been to investigate and verify finite element models for simulation of the fabrications of two types of pipe joints. READ MORE

3. Modelling and simulation of mechanical cutting
Abstract : The commercial success of a new product is influenced by the time to market. Shorter product lead-times are of importance in a competitive market.This can be achieved only if the product development process can be realised in a relatively small time period. READ MORE

4. Thermal impact on rolling contact fatigue of railway wheels
Abstract : Rolling contact fatigue (RCF) is a very common and costly damage mechanism for rails and wheels. This thesis investigates the influence of combined thermal and mechanical loading on RCF of railway wheels on the basis of numerical predictions. READ MORE

5. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components
Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.
