6. Rotational Bands and Pairing Interaction in the Shell Model
Sammanfattning : One of the goals pursued in the present research was to understand the nuclear phenomena (such as rotational bands, their backbending and termination, deformation, pairing correlations, etc.) using different views provided by different nuclear models. LÄS MER
7. Microscopic Properties of Superdeformed Nuclei
Sammanfattning : Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. LÄS MER
8. Deformation and failure of rock
Sammanfattning : In this doctoral thesis work the relationship between the deformation and the initiation of failure around an underground excavation was studied. In this work data from observed failure and measured deformations was used. This work is based on information obtained from laboratory test, underground field cases and numerical analysis. LÄS MER
9. Surface Integrity of Case-hardened Gears - with Particular Reference to Running-in and Micropitting
Sammanfattning : A gearbox with gears of different sizes is part of a vehicle transmission system and plays an important part in transmitting the engine power to the wheels. The efficient energy transmission highly relies on the performance of gears. Together, the mesh efficiency and durability determines the performance of gears. LÄS MER
10. Microstructural changes in high strength steels exposed to large deformation and high strain rates
Sammanfattning : Increasing steel prices and environmental aspects have put forward the demand to reduce material consumption and energy usage in manufacturing industry and near-net-shape manufacturing techniques have thus become increasingly important. High-velocity parting-off,high-velocity forming and cold ring rolling are three such manufacturing methods that exhibit great potentials in terms of material waste reduction. LÄS MER
