1. Wheel-rail contact modelling in vehicle dynamics simulation
Sammanfattning : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. LÄS MER

3. On indentation methods for characterization of inelastic materials
Sammanfattning : .... LÄS MER
4. Influence of thermal loading on mechanical properties of railway wheel steels
Sammanfattning : Material integrity and properties of wheels are critical in railway traffic, as wheels fulfil the important function of transferring load and traction from the vehicle to the rail track. Steels with a pearlitic microstructure are commonly used for wheels due to their height strength, low cost and good wear properties. LÄS MER
5. Development of New Multiscale Polymer Composites for Water Lubricated Tribological Contacts
Sammanfattning : Moving towards a Green Economy, there is a growing demand to use environmentally friendly tribological systems that has resulted in industries turning towards new mate-rials and water-based lubrication to satisfy their needs. Considering the low viscosity of water, tribological contacts lubricated with it are likely to operate in boundary/mixed lubrication regime for relatively long periods. LÄS MER
