1. Identification and synthesis of components for uncertainty propagation
Abstract : For automotive structures, built-up of hundreds of components with property spread, knowing the effects of component variability and its propagation through the system assembly is important in order to mitigate noise and vibration problems. To increase the understanding of how the spread propagates into variability in built-up structures, both experimental and computational aspects are considered in this thesis. READ MORE

2. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data
Abstract : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibrations. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be modified. READ MORE

3. Systematic planning and execution of finite element model updating
Abstract : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. READ MORE

4. Structural Reliability and Identification with Stochastic Simulation - Application to Railway Mechanics
Abstract : System identification of structures based on measured response data can play a key role in improving reliability based structural designs. However, the experimental limitations of in situ tests and uncertainties of required model complexity together with the inverse nature of system identification give rise to a number of challenging issues.
