1. Microstructural aspects of the ductile-to-brittle transition in pressure vessel steels
Sammanfattning : .... LÄS MER
2. 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
3. Numerical models of ductile crack growth
Sammanfattning : .... LÄS MER
4. Ductile damage modeling of the machining process
Sammanfattning : Machining processes are among the most common manufacturing processes for producing components used on a daily basis. It is a complex material removal process. Today, the research and development within the manufacturing industry is addressed by cost efficient numerical simulation strategies rather than by costly experimental procedures. LÄS MER
5. Computational modelling of machining - Mesh objective ductile damage modelling
Sammanfattning : AbstractTo strengthen the competitiveness the manufacturing industry strives for a continuousdevelopment of cost efficient manufacturing processes and improved product quality.These research and development issues are addressed by increasing the implementationof simulation tools based on finite element method (FEM).
