11. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach
Abstract : Numerical simulation of rolling contact serves as an important complement to laboratory and full-scale testing in the endeavour to further the understanding of related physical mechanisms, e.g. the influence of friction on the rolling motion, the thermomechanical interaction, damage phenomena and related modes of failure.

12. Numerical analysis of coalescence-induced jumping droplets on superhydrophobic surfaces
Abstract : Bio-inspired superhydrophobic surfaces are used in numerous technological applications due to their self-cleaning ability. One of the several mechanisms reported in literature and responsible for self-cleaning is the phenomenon of coalescence-induced jumping of droplets from such surfaces. READ MORE

13. A Novel Fiber Interaction Method for Simulation of Early Paper Forming
Abstract : In the forming section of a paper machine, a fiber suspension is flowing down onto a forming fabric, and a paper structure is formed. By using computer simulations this process can be studied, attaining new knowledge helping to improve paper quality and machine efficiency. READ MORE

14. 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

15. Initiation of rolling contact fatigue from asperities in elastohydrodynamic lubricated contacts
Abstract : Rolling contacts are utilized in many technical applications, both in bearings and in the contact between gear teeth. These components are often highly loaded, which makes them susceptible to suffer from rolling contact fatigue. This work focuses on the rolling contact fatigue mechanism of pitting. READ MORE
