16. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals
Abstract : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. READ MORE

17. Investigation of the correlation of fracture frequency and electric resistivity in impact craters in crystalline rocks
Abstract : Impact craters are formed when a large meteorite or comethits the Earth. At the impact a shock wave is released causingabundant fracturing in the surrounding bedrock. This type offracturing is intense and occurs throughout a very large volume(>100 km3) of the bedrock. READ MORE

18. Wood and fibre mechanics related to the thermomechanical pulping process
Abstract : The main objective of this thesis was to improve the understanding of some aspects on wood and fibre mechanics related to conditions in the thermomechanical pulping process. Another objective was to measure the power distribution between the rotating plates in a refiner. READ MORE

19. Exercise in Youth and Long-Term Effects on Bone and Joints
Abstract : Partly due to an ageing population, the number of osteoporosis-related fractures and osteoarthritis (OA)-related hip and knee arthroplasty procedures is increasing. The individual suffering and the burden on society for these conditions is immense. READ MORE

20. The fracture mechanisms in duplex stainless steels at sub-zero temperatures
Abstract : The aim of the thesis was to study the susceptibility for brittle failures and the fracture process of duplex stainless steels at sub-zero temperatures (°C). In the first part of the thesis plates of hot-rolled duplex stainless steel with various thicknesses were used to study the influence of delamination (also known as splits) on the fracture toughness.
