1. Sprickor i gemenskapen
Sammanfattning : Cracks in the Spirit of Community is a study of a Swedishtrade union in a period of change. Increasingly, traditionaltrade unions´ work based on collective solutions has comeinto question, and the customer perspective of trade unionactivities is becoming more prominent. LÄS MER
2. Finite Element Methods for Interface Problems
Sammanfattning : This thesis focuses on computationally efficient methods for flow in fractured porous media. Two approaches are presented where the interface is embedded on the underlying finite element mesh. The methods allow for representation of the interface geometry from the underlying discretization and with discontinuities across the interface. LÄS MER
3. Processability of Laser Powder Bed Fusion of Alloy 247LC-Influence of process parameters on microstructure and defects
Sammanfattning : This thesis is about laser powder bed fusion (L-PBF) of the nickel-basedsuperalloy Alloy 247LC. Alloy 247LC is mainly used in gas turbine blades and processing the blades with L-PBF may confer performance advantage over the blades manufactured with conventional methods. LÄS MER
4. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements
Sammanfattning : 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. LÄS MER
5. Modelling of Transport Processes Involved in Service Life Prediction of Concrete : Important Principles
Sammanfattning : The main focus in this licentiate thesis is a description of the environmentally introduced action of diffusing and chemically reactive (e.g. carbonation and chemical-physical adsorption-desorption) matter in the pore solution and in the air-filled space in the pore system of the material.
