1. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars
Sammanfattning : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. LÄS MER

3. Splitting of concrete in the anchoring zone of deformed bars : a fracture mechanics approach to bond

4. Anchorage of naturally-corroded, plain bars in Reinforced Concrete structures
Sammanfattning : Reinforced Concrete (RC) is the most common construction material in existing structures. However, RC structures are susceptible to deterioration over time, with corrosion of the reinforcing steel as most common mechanism. Corrosion reduces strength and ductility provided by the reinforcement bars and affects their interaction with the concrete. LÄS MER
5. Modeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel
Sammanfattning : Large shear strains accumulate in the near-surface region under the running band of railway rails. In this region, rolling contact fatigue cracks often initiate, causing major problems for the railway industry. LÄS MER
