16. Oxidation induced failure of superalloys: High temperature crack growth and oxide scale properties
Sammanfattning : Gas turbine materials are designed to work in extreme environments in high temperature with an oxidising environment and variable mechanical loading. The study of high temperature fatigue properties of these materials is therefore important. LÄS MER
17. Micromechanical modeling of cleavage fracture in polycrystalline materials
Sammanfattning : Cleavage fracture in ferritic steels can be defined as a sequence of few critical steps. At first nucleation of a microcrack takes place, often in a hard inclusion. This microcrack then propagates into the surrounding matrix material. The last obstacle before failure is the encounter of grain boundaries. LÄS MER
18. 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
19. Evaluation of Splitting Capacity of Bottom Rails in Partially Anchored Timber Frame Shear Walls
Sammanfattning : The horizontal stabilization of timber frame buildings is oftenprovided by shear walls. Plastic design methods can be used todetermine the load-carrying capacity of fully and partially anchoredshear walls. In order to use these methods, a ductile behaviour of thesheathing-to-framing joint must be ensured. LÄS MER
20. Reliability-based Assessment of Concrete Dam Stability
Sammanfattning : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. LÄS MER
