1. Localization of Finite Element Model Errors : Error Criteria and Identifiability
Sammanfattning : .... LÄS MER
2. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach
Sammanfattning : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. LÄS MER
3. Model Adaptivity in Elasticity
Sammanfattning : We consider model adaptivity in elasticity for dimensionally reduced forms, and shall treat different conceptual approaches. The basic idea, however, is to adaptively refine, not only the computational mesh, but also the underlying mathematical formulation. LÄS MER
4. Active Muscle Responses in a Finite Element Human Body Model
Sammanfattning : The development of automotive safety systems is moving towards an integration of systems thatare active before and during an impact. Consequently, there is a need to make a combinedanalysis of both the pre-crash and the in-crash phases, which leads to new requirements forHuman Body Models (HBMs) that today are used for crash simulations.

5. Stochastic model updating and model selection with application to structural dynamics
Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.
