21. RoPax Ship Collision – a Methodology for Survivability Analysis
Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER
22. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance
Sammanfattning : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. LÄS MER
23. Modelling, failure modes prediction and optimization of gear shifting mechanism, Application to heavy vehicle transmission systems
Sammanfattning : The transmission system has a key role to drive a vehicle transmitting power from engine to rotational motion at wheels. Gear shifting mechanism inside the gearbox is a crucial part of the transmission system. LÄS MER
24. Modelling of Failure in High Strength Steel Sheets
Sammanfattning : In this theses the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M are studied. Constitutive laws and failure models are calibrated and veried by the use of experiments and numerical simulations. LÄS MER
25. Linear and Nonlinear Mechanics of Lattice Materials : Computational Modelling and Experiments
Sammanfattning : Lattice materials are artificial materials made of repeating unit-cells. The internal architecture of these materials can be engineered for a specific application such as energy absorption, heat transfer, or acoustic damping. LÄS MER
