1. Adhesive Joints in Timber Engineering. Modelling and Testing of Fracture Properties
Abstract : This thesis, which is a compilation of seven papers, concerns the mechanical testing, numerical analysis and constitutive modelling of wood-adhesive bonds in timber engineering. Applications such as finger-joints, glued-laminated timber and glued-in rods are considered. READ MORE

2. Effect of Physical Activity on Bone, Muscle and Fracture Risk during Growth
Abstract : Osteoporosis and related fractures are a global health problem. Physical activity, especially during growth, has been suggested as a strategy to improve musculoskeletal health in the population. READ MORE

3. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses
Abstract : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. READ MORE

4. Micromechanical modeling of cleavage fracture in polycrystalline materials
Abstract : Cleavage fracture in ferritic steels can be defined as a sequence of few critical steps. At first nucleation of a microcrack takes place, often in a hard inclusion. This microcrack then propagates into the surrounding matrix material. The last obstacle before failure is the encounter of grain boundaries. READ MORE

5. Stability and sorption capacity of montmorillonite colloids : Investigation of size fractional differences and effects of γ-irradiation
Abstract : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. READ MORE
