1. Isotope-Selective Spectroscopy: Fast Timing R&D and fp-Shell Mirror Isomers
Abstract : This thesis highlights the research and development of a new plastic-scintillator detector for time-of-flight measurements in relativistic heavy-ion beam experiments. The detector makes possible the identification of different ion species on flight distances as short as a few meters. READ MORE

2. Evaluation of Splitting Capacity of Bottom Rails in Partially Anchored Timber Frame Shear Walls
Abstract : The horizontal stabilization of timber frame buildings is oftenprovided by shear walls. Plastic design methods can be used todetermine the load-carrying capacity of fully and partially anchoredshear walls. In order to use these methods, a ductile behaviour of thesheathing-to-framing joint must be ensured. READ MORE

3. Simplified mechanical models for the nonlinear dynamic analysis of elasto-plastic steel structures impacted by a rigid body
Abstract : Buildings subjected to impact and explosion are usually studied using large scale and highly nonlinear finite element model which are time-consuming. The first part of the thesis deals with the development of simple and accurate models for evaluating the nonlinear inelastic behaviour of steel frame structures subjected to impact. READ MORE

4. Parametric FE-modelling of non-linear racking behaviour of light-frame shear walls and modules used for multi-storey timber buildings
Abstract : Wood is a sustainable material from nature that has a longstanding traditionas a building material. Compared to other construction materials, such as steeland concrete, the significance of using structural timber and engineered wood products has increased in recent years because they are regarded as a renewable source and require a low carbon footprint and less energy consumption during production.

5. Co-rotational beam elements in instability problems
Abstract : The purpose of the work presented in this thesis is to implement co-rotational beam elements and branch-switching procedures in order to analyse elastic and elastoplasticinstability problems. For the 2D beam elements, the co-rotational framework is taken from Crisfield [23]. READ MORE
