1. Steel Fibres in Reinforced Concrete Structures of Complex Shapes: Structural Behaviour and Design Perspectives
Sammanfattning : In concrete structures of complex geometries, the formability of concrete is an asset.However, complex geometries introduce time-demanding form and reinforcement works. LÄS MER
2. Reinforcement in Tailor-made Concrete Structures
Sammanfattning : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. LÄS MER
3. On Postbuckling Analysis of Thin-walled Structures Numerical and Statistical Approaches
Sammanfattning : Thin-walled structural elements, such as plates, shells and beams are important load carrying components in civil-, mechanical-, automotive- aeronautical- and marine engineering structures. In order to reduce the weight thin-walled structures are given an optimum design making them sensitive to unforeseen deviations in geometry, boundary conditions, material properties and applied loads.

4. Studies on boundary values of eigenfunctions on spaces of constant negative curvature
Sammanfattning : This thesis consists of two papers on the spectral geometry of locally symmetric spaces of Riemannian and Lorentzian signature. Both works are concerned with the idea of relating analysis on such spaces to structures on their boundaries.The first paper is motivated by a conjecture of Patterson on the Selberg zeta function of Kleinian groups.

5. Application of X-ray Computed Tomography for Assessment of Additively Manufactured Products
Sammanfattning : Additive Manufacturing (AM) is a novel method for fabricating parts from three-dimensional model data, usually by joining materials in layer upon layer fashion. The freedom of design in this method has resulted in new possibilities for fabrication of parts with complex geometries. LÄS MER
