1. Analysis of Ball CV-joints of Fixed Type
Abstract : Two theoretical models for analysing ball CV-joints of fixed type are presented. The models, which have been implemented in computer programs, calculate internal conditions such as load distribution, contact angles and displacements for different operating conditions. READ MORE

2. Time-domain modelling of high-frequency wheel/rail interaction
Abstract : The interaction between wheel and rail is the predominant source of noise emission from railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail noise concerns rolling noise and impact noise caused by the vertical interaction excited by roughness and discrete irregularities of the wheel/rail running surfaces, respectively.

3. 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.

4. The Friction between Paper Surfaces
Abstract : The main objective for the work described in this PhD thesiswas to formulate a friction model to characterize thefrictional behavior of paper. More specifically, the modelshould explain a phenomenon that is typical for paper grades,viz.: that the level of paper-to-paper friction is dependent onthe direction and the number of previous slides.

5. Probing Interactions between Bio-Fibre Components
Abstract : I den här avhandlingen har atomkrafts mikroskopi (AFM) och kvartskristall mikrovåg med dissipation (QCM-D) används för att undersöka interaktioner i bio-fiber modell system av cellulosa och xyloglukan (XG); en naturligt förekommande polysackarid viktig för tillväxt av träd och andra växter. Dessutom har det avgörande momentet av friktionskrafts-kalibrering studerats för att erhålla noggranna och kvantitativa resultat med kolloidal prob AFM. READ MORE
