Populærvitenskapelig sammendrag av avhandlingen
The title of the thesis is “Some new contributions related to structural problems in engineering”.
This PhD-thesis consist of five papers covering a broad spectrum of topics within engineering sciences, which are of interest also in pure mathematics. During this work a close collaboration between the research institute SINTEF Narvik and UiT has made it possible to study important topics concerning concrete dams. The results can in the future contribute to a better understanding of the assessment of structural stability and how these dams can be modelled. Another topic that has been investigated is beams resting on non-linear elastic foundation, examples of these types of structures are railway tracks, and it can also be used to model ice sheets on water. The latter example is also of interest when it comes to understand how the load from the ice is transferred to structures such as dam constructions. Furthermore, anisotropic plate structures have been studied, these types of plates are used in structures where there is a need for high structural capacity but also one wishes to reduce the weight of the plate. Moreover, important contribution to the field of Fourier analysis have been made. Fourier analysis have been used to describe important phenomena such as crack propagation, strength etc. for dams, bridges and tunnels. We hope to apply these theoretical results in future research in collaboration with SINTEF Narvik and the industry in northern Norway.
