16. Fracture mechanics and tribology of rock and rock joints
Sammanfattning : In the first part of the thesis fracture toughness tests of rocks are described. Specimens of Stripa Granite have been tested in three point bending, compact tension and short rod tension. LÄS MER
17. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing
Sammanfattning : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. LÄS MER
18. High-Temperature Durability Prediction of Ferritic-Martensitic Steel
Sammanfattning : Materials used for high-temperature steam turbine sections are generally subjected to harsh environments with temperatures up to 625 °C. The superior creep resistance of 9–12 % Cr ferritic-martensitic steels makes them desirable for those critical steam turbine components. LÄS MER
19. The role of microstructure for crack propagation in cortical bone
Sammanfattning : Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. LÄS MER
20. A Fracture Mechanics Approach to Study Hydrogen Embrittlement in High Strength Martensitic Steels
Sammanfattning : High strength steels that are subjected to hydrogen experience embrittlement where the mechanical properties are reduced, and premature failure of components may occur. Although the phenomenon has been recognized for over 150 years, it is not clear what drives embrittlement. LÄS MER
