    Abstract : 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. READ MORE

  2. 2. Thermomechanical Modelling of Tribological Systems

    Author : Niclas Strömberg; Alain Curnier; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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.

  4. 4. Thermomechanics of block brakes

    Author : Daniel Thuresson; Chalmers University of Technology; []
    Keywords : friction; pin model; contact mechanics; brake; thermo camera; thermomechanical; wear; freight train.; finite element; temperature measurement;

    Abstract : Friction in sliding contacts plays an important role in tribology. Applications can be found in many engineering fields  such as braking of vehicles  in which friction brakes are by far the most common. Thus, an understanding of the mechanisms involved in friction brakes has become more important as the demands on brakes increase. READ MORE

  5. 5. Efficient thermomechanical modelling of welding

    Author : Lars Wikander; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : 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. READ MORE
