16. Materials Reliability in PEM Fuel Cells
Sammanfattning : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. LÄS MER
17. A NEW APPROACH TO CRACK CONTROL FOR REINFORCED CONCRETE - An investigation of crack widhts close to the reinforcement and the correlation to service life
Sammanfattning : 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. LÄS MER
18. Structural Effects of Reinforcement Corrosion in Concrete Structures
Sammanfattning : Reinforcement corrosion is a common cause of deterioration in reinforced concrete.The corrosion mechanism involved and the consequent structural behaviour ofdeteriorated reinforced concrete members have been studied by several researchers. LÄS MER
19. Structural Behaviour of Deteriorated Concrete Structures
Sammanfattning : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. LÄS MER
20. Simulation of multipass welding to reduce intergranular stress corrosion cracking
Sammanfattning : This thesis describes the use of the finite element method for simulation of multipass welding. The simulations have been used to find welding procedures that minimises tensile residual stresses on the inside of the studied pipes. This will lead to a reduced risk for Inter Granular Stress Corrosion Cracking. LÄS MER
