1. Computational homogenisation and solution strategies for phase-field fracture
Abstract : 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. READ MORE

2. Numerical methods and multi-scale modeling for phase-field fracture - With applications in linear elastic and poro-elastic media
Abstract : 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. READ MORE

3. Phase field modeling of flaw-induced hydride precipitation kinetics in metals
Abstract : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. READ MORE

4. Phase-field modeling of stress-induced precipitation and kinetics in engineering metals
Abstract : The formation of brittle compounds in metals operating in corrosive environments can be a tremendous source of embrittlement for industrial structures and such phenomenon is commonly enhanced in presence of stresses. To study this type of microstructural change modeling is preferred to experiment to reduce costs and prevent undesirable environmental impacts. READ MORE

5. Multiphase continuum modeling of wood : A hybrid mixture theory approach
Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE
