1. Microstructural aspects of the ductile-to-brittle transition in pressure vessel steels
Sammanfattning : .... LÄS MER
2. Micromechanical modeling of cleavage fracture in polycrystalline materials
Sammanfattning : Cleavage fracture in ferritic steels can be defined as a sequence of few critical steps. At first nucleation of a microcrack takes place, often in a hard inclusion. This microcrack then propagates into the surrounding matrix material. The last obstacle before failure is the encounter of grain boundaries. LÄS MER
3. Numerical models of ductile crack growth

4. Modeling framework for ageing of low alloy steel
Sammanfattning : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. LÄS MER
5. Modeling of structural integrity of aged low alloy steels using non-local mechanics
Sammanfattning : Ageing of low alloy steels affects the structural integrity assessment as it most commonly causes embrittlement and a hardening of the material. This is due to theevolution of the microstructure during operation in the specific application. LÄS MER
