1. Stainless steel plasticity : material modelling and structural applications
Sammanfattning : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. LÄS MER
2. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression
Sammanfattning : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

3. Plastic behaviour of steel : experimental investigation and modelling
Sammanfattning : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. LÄS MER
4. A Study on Particle Motion and Deposition Rate : Application in Steel Flows
Sammanfattning : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. LÄS MER
5. Bracing of steel bridges during construction; theory, full-scale tests and simulations
Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.
