11. Mechatronic aspects of an innovative two-axle railway vehicle
Sammanfattning : Within the Shift2Rail research program the goals for a sustainable growth of the railway sector are set. Among these are substantial reduction of Life Cycle Costs, improved reliability and energy efficiency, the reductionof noise emissions, and the achievement of full interoperability of the rolling stock.

12. Shear cracks in concrete structures subjected to in-plane stresses
Sammanfattning : After only two years of service, extensive cracking was found in the webs of two light-rail commuter line bridges in Stockholm, the Gröndal and Alvik bridges. Due to this incident it was found necessary to study the means available for analysing shear cracking in concrete structures subjected to in-plane stresses. LÄS MER
13. Experimental characterization and numerical modeling of compression perpendicular to the grain in wood and cross-laminated timber
Sammanfattning : Compression perpendicular to the grain (CPG) of wood is a typical loading situation in timber structures. It has been an extensively studied research topic for decades, due to the highly ductile behavior of wood under such loading, the large variations in mechanical properties, and the relevance of these properties in structural design.

14. Modeling of evolving anisotropy at finite elasto-plastic strain
Sammanfattning : Simulation tools are used to a wide extent in the product development process today, both to obtain better products and to reduce the development time required. Anisotropic materials are utilized in many engineering applications. LÄS MER
15. Physically based models of metal plasticity
Sammanfattning : This work is focussing on the material modelling aspects in simulation of forming processes. The research question is: Do physical based material models have any advantages compared to the more common type of engineering models used in simulation of forming processes? The success of performing useful simulations of forming processes depends very much on the accuracy of the used material description. LÄS MER
