1. 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
2. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses
Sammanfattning : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. LÄS MER
3. Benefits of strengthening timber with fibre-reinforced polymers
Sammanfattning : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. LÄS MER
4. Dynamic Behaviour of Reinforced Concrete Structures: Analyses with a Strong Discontinuity Approach
Sammanfattning : Reinforced concrete is a widely used construction material. To obtain efficient design of new structures and to verify the real mechanical behaviour of existing ones, it is necessary to improve the understanding of advanced structural analyses of reinforced concrete structures.

5. Strengthening of timber structures with flax fibres
Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER
