6. Pure shear fracture of brittle rock : a theoretical and laboratory study
Abstract : This doctoral thesis deals with determination of Mode II fracture toughness, KIIc, for rock. Three types of specimens, antisymmetric four-point bending, direct shearing and compression-shear specimens, are experimentally and numerically investigated. READ MORE

7. Mechanical Characterization of Heterogeneous Brittle Materials
Abstract : Comminution is one of the highest energy-consuming processes in the mining and mineral processing industry by consuming around 2% of the global generated energy with an overall efficiency of 1-3%. Different approaches to the optimization of processes have been developed, but there is still room for improvement. READ MORE

8. On Crack Dynamics in Brittle Heterogeneous Materials
Abstract : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. READ MORE

9. 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

10. 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
