1. Plastic instability analysis of plane frames using a co-rotational approach
Sammanfattning : .... LÄS MER
2. Co-rotational beam elements in instability problems
Sammanfattning : 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]. LÄS MER
3. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction
Sammanfattning : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. LÄS MER
4. Energy-momentum conserving time-stepping algorithms for nonlinear dynamics of planar and spatial Euler-Bernoulli/Timoshenko beams
Sammanfattning : Large deformations of flexible beams can be described using either the co-rotational approach or the total Lagrangian formalism. The co-rotational method is an attractive approach to derive highly nonlinear beam elements because it combines accuracy with numerical efficiency. LÄS MER
5. End-Shield Bridges for High-Speed Railway : Full scale dynamic testing and numerical simulations
Sammanfattning : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.
