1. Modelling of frictional joints : from dissipative mechanisms to structural response
Sammanfattning : .... LÄS MER
2. Time-domain modelling of curve squeal: a fast model for one- and two-point wheel/rail contact
Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. A single frequency, corresponding to a wheel mode, dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER
3. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach
Sammanfattning : 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. Engineering model for curve squeal formulated in the time domain
Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. Squeal is common in curves of a radius lower than 200 meters. A single frequency dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER
5. Frictional Effects on Hertzian Contact and Fracture
Sammanfattning : This thesis addresses normal axisymmetric contact of dissimilar elastic solids at finite interfacial friction. It is shown that in the case of smooth and convex but otherwise arbitrary contact profiles and monotonically increasing loading a single stick-slip contour evolves being independent of loading and profile geometry.
