1. Experiments and modelling of fracture initiation at impact
Sammanfattning : The thesis addresses different questions, each necessary in the understanding of dynamic fracture initiation and crack propagation in steel. Emphasis lays on dynamic crack propagation experiments performed in the ductile to brittle transition region and possible conclusions, that can be drawn from them. LÄS MER
2. Computational homogenisation and solution strategies for phase-field fracture
Sammanfattning : The computational modelling of fracture not only provides a deep insight into the underlying mechanisms that trigger a fracture but also offers information on the post-fracture behaviour (e.g., residual strength) of engineering materials and structures. LÄS MER
3. Microstructural aspects of the ductile-to-brittle transition in pressure vessel steels
Sammanfattning : .... LÄS MER
4. Fracture toughness properties of a welded duplex stainless steel
Sammanfattning : .... LÄS MER
5. Pure shear fracture of brittle rock : a theoretical and laboratory study
Sammanfattning : This doctoral thesis deals with determination of Mode II fracture toughness, KIIc, for rock. Three types of specimens, antisymmetric four-point bending, direct shearing and compression-shear specimens, are experimentally and numerically investigated. LÄS MER
