11. Investigations of unconventional marine structures by the finite element method
Sammanfattning : .... LÄS MER
12. Coining Residual Stresses in Aluminium Ship Structures: Experiments and FE- simulations
Sammanfattning : The build-up and redistribution of residual stresses obtained by stress coining of aluminium plates containing a hole have been studied experimentally and numerically. The foil strain gauge technique has been employed to measure strains at the bore of a hole during and after the coining process. LÄS MER
13. Impact Loading of Composite and Sandwich Structures
Sammanfattning : Low weight is one of the most important factors in the design process of high speed naval ships, road vehicles and aircrafts. Lower structural weight enables the possibility of down-sizing the propulsion system and thus decrease manufacturing and operating costs as well as reducing the environmental impact. LÄS MER
14. Dynamics of Vehicle-Deck Interactions
Sammanfattning : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. LÄS MER
15. Methods for the Evaluation of Wingsails with a Crescent-Shaped Profile
Sammanfattning : Seaborne transportation accounts for a large proportion of greenhouse gas (GHG) emissions. The International Maritime Organization (IMO) has stipulated that GHG emissions should be reduced by 50% before 2050 compared to 2018. The use of wind-assisted ship propulsion (WASP) is considered one of the most effective ways to reduce GHG emissions. LÄS MER
