1. 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.

2. Modelling of forming and quenching of ultra high strength steel components for vehicle structures
Sammanfattning : The doctoral thesis deals with modelling and simulations in integrated product and process development. The research concerns with development of models and methods for simulation of component manufacturing and product functionality. LÄS MER
3. Modeling of material behavior in metal forming
Sammanfattning : With an increasing demand to improve efficiency and to cut costs, the industry is constantly seeking to reduce the time and money spent in product development and manufacturing. Use of computer-based simulations has become more or less a standard tool to meet this demand. LÄS MER
4. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing
Sammanfattning : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. LÄS MER
5. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping
Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER
