1. 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
2. Induction heating of carbon fibre reinforced polymer composites : Characterization and modelling
Sammanfattning : Carbon fibre reinforced polymers (CFRP) are lightweight materials with great potential due to their high strength and stiffness relative to their weight. This enables weight reduction in, for example, vehicles, which is important in reducing energy consumption. LÄS MER
3. Carbon fibre reinforced polymers for strengthening of structural elements
Sammanfattning : There is a large need for strengthening of concrete structures all around the world. There can be many reasons for strengthening, increased loads, design and construction faults, change of structural system, and so on. The need exists for both strengthening in flexure as well as in shear. LÄS MER
4. FRP shear strengthening of reinforced concrete beams
Sammanfattning : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

5. On Cohesive Modelling of Carbon/Epoxy Composites : Delamination and Fibre Compressive Failure
Sammanfattning : Carbon Fibre Reinforced Polymers are widely used in engineering applications where weight saving and high mechanical performance are a key factors. However, an inheren tweakness of laminated CFRP:s is there relatively low resistance to delamination. Therst part of this thesis is devoted to extract cohesive laws associated with delamination.
