21. Solid metal induced embrittlement of titanium alloys
Sammanfattning : Titanium alloys were for a time believed to be highly resistant to environmentally assisted cracking because of their ability to form a protective oxide film on the surface. Their resistance can still be considered to be high, but when cracking resistance was originally defined to ensure reliable functionality of fracture-critical components, certain conditions that promote cracking were discovered.

22. Analysis of thermal shock in brittle materials
Sammanfattning : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. LÄS MER
23. On structural integrity with emphasis on rate effects of fracture toughness
Sammanfattning : This thesis is concerned with structural integrity from a fracture mechanics point of view. The emphasis in this work is on rate effects of fracture toughness but all investigations deal with phenomena or problems within the frame work of non-linear fracture mechanics. LÄS MER
24. Failure of thinwalled structures under impact loading
Sammanfattning : Thinwalled structures are widely used for different applications, e.g. maritime structures,vehicles, off-shore structures, aircraft fuselage, ship panels etc., and due to their applicationthey might be exposed to high strain rate loads as blast loads. LÄS MER
25. Modeling and Simulation of Weld Hot Cracking
Sammanfattning : Several alloy systems are susceptible to weld hot cracking. Weld hot cracking occurs by fracture of liquid films, normally grain boundary liquid films, at the late stage of the solidification of the weld. The cracks can be small and therefore difficult to detect by nondestructive test methods. LÄS MER
