16. Multiscale modeling of dynamic recrystallization
Sammanfattning : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. LÄS MER
17. Multiscale and multiphase methods for wave propagation
Sammanfattning : .... LÄS MER
18. Multiscale models and simulations for diffusion and interaction in heterogeneous domains
Sammanfattning : We investigate multiscale and multiphysics models for evolution systems in heterogeneous domains, with a focus on multiscale diffusions. Although diffusion is often studied in terms of continuum observables, it is a consequence of the motion of individual particles. LÄS MER
19. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media
Sammanfattning : This thesis presents novel numerical methods and a multi-scale modelling framework tailored for advancing the phase-field fracture model with applications in linear elastic and poro-elastic media. In the realm of the numerical methods, the focus lies on devising computationally efficient and robust monolithic solution techniques. LÄS MER
20. Numerical Analysis of Evolution Problems in Multiphysics
Sammanfattning : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.
