1. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment
Sammanfattning : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. LÄS MER
2. Visually induced ocular torsion
Sammanfattning : There has been some controversy whether ocular torsion (eye rotation around the line of sight) is induced in response to a tilted visual scene. The aim of this thesis was to investigate if ocular torsion can be induced by viewing a tilted visual scene and to evaluate the effect of different stimuli parameters on the torsional response.

3. Studies in field theory : supersymmetry and torsion potentials
Sammanfattning : This report contains introductions to and summaries of the papers which constitute my thesis. These papers treat four different topics: The first of these is the superspace treatment of the linear multiplet in six space-time dimensions, in particular the solution of the constraint for this multiplet.

4. Shear and Torsion Interaction in Prestressed Hollow Core Slabs
Sammanfattning : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

5. Dynamic higher order equations
Sammanfattning : The subject of this thesis is to derive and evaluate governing equations and correspondingboundary conditions for solid cylinders and rectangular plates, where the materialconstituting the cylinder or plate are governed by classical elasticity, micropolar elasticityor a functionally graded case of the previously mentioned models. This is achieved by asystematic power series expansion approach, by either adopting a generalized Hamilton'sprinciple or a direct approach. LÄS MER
