1. Thermomechanical behaviour of tread braked wheels
Sammanfattning : Tread brakes, also known as block brakes, are a type of friction brakes commonly used in the railway industry. They are a low-cost and low-maintenance solution compared to more complicated systems such as disc brakes or electrodynamic brakes. LÄS MER
2. Wood and fibre mechanics related to the thermomechanical pulping process
Sammanfattning : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. LÄS MER
3. Thermomechanical Modelling of Tribological Systems
Sammanfattning : The present thesis concerns the thermomechanical modelling of contact, friction and wear. Within a framework of continuum thermodynamics, Signorini's contact conditions, Coulomb's law of friction and Archard's law of wear are derived by means of a free energy and a dissipation potential.

5. Efficient thermomechanical modelling of welding
Sammanfattning : This thesis deals with the pursuit of simple and efficient models for the prediction of welding residual deformation and stress, in particular ways to reduce the computational effort spent on the analysis. In the first part of the thesis, finite element models which reduce the number of degrees of freedom and thereby the execution time are presented. LÄS MER
