1. Numerical Modeling of Plasticity in FCC Crystalline Materials Using Discrete Dislocation Dynamics
Abstract : Plasticity in crystalline solids is controlled by the microscopic line defects known as “dislocations”. Decisive role of dislocations in crystal plasticity in addition to fundamentals of plastic deformation are presented in the current thesis work. READ MORE

2. Numerical Modelling of Short Fatigue Crack Growth
Abstract : Fatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. READ MORE

4. Multiscale modelling of radiation-enhanced diffusion phenomena in metals
Abstract : A multiscale modelling framework and an experiment campaign are used to study void swelling and Cu precipitation under irradiation. Several aspects regarding defect and solute diffusion under irradiation have been studied in this thesis. READ MORE

5. Atomistic simulations of lattice defects
Abstract : Mechanical properties of solids are governed by crystal imperfections. Computational materials science is largely concerned with the modelling of such defects, e.g. their formation, migration, and interaction energies. READ MORE
