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. Analysis of thermal shock in brittle materials
Abstract : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. READ MORE

3. Deformation and failure of brittle rocks under compression
Abstract : This thesis describes the deformation and failure of rocks under compression through a micromechanics model and laboratory studies of the Kaiser effect. It comprises an overview and seven appended papers. The deformation model is developed based on the analysis of the behaviour of microcracks. READ MORE

4. Simulation of the progressive failure of brittle rock
Abstract : The anisotropic response of a brittle rock due to the formation of cracks under general applied loads has been taken as a continuous phenomenon on a suitable macroscopic scale. The response is described by a continuum field variable called the "damage vector". READ MORE

5. Mechanical characterization and modelling of the fracture behaviour of thin brittle coatings on polymer films
Abstract : Thin brittle coatings with thickness of a few nanometres deposited on flexible polymer substrates form an interesting material combination for food packaging and flexible electronics. This combination may enhance the barrier performance in carton packages. In flexible electronics, coatings could conduct electricity despite their small thickness. READ MORE
