1. Control of Cracking due to Imposed Strains in Concrete Structures
Abstract : This thesis is concerned with crack control due to imposed deformations in concrete structures. The objective of crack control may either be to prevent cracking or to limit the crack widths. The aim here is to increase the knowledge in both fields for some common structures. Five papers are included and the three last concern crack development. READ MORE

2. Initiation and early crack growth in VHCF of stainless steels : Experimental and theoretical analysis
Abstract : Mechanical fatigue is a failure phenomenon that occurs due to repeated application of mechanical loads. Very High Cycle Fatigue (VHCF) is considered as the domain of fatigue life greater than 10 million load cycles. READ MORE

3. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements
Abstract : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. READ MORE

4. Multistage gearboxes : vibration based quality control
Abstract : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. READ MORE

5. A NEW APPROACH TO CRACK CONTROL FOR REINFORCED CONCRETE - An investigation of crack widhts close to the reinforcement and the correlation to service life
Abstract : One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. READ MORE
