1. Structural Design of Laser-Welded Sandwich Panels for Marine Applications
Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.

2. Stainless steel plasticity : material modelling and structural applications
Sammanfattning : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. LÄS MER
3. Welding of Heavy Structures Subjected to Fatigue
Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link of the structure since fatigue fractures in welds are a common cause for failures. This thesis proposes several changes in order to improve the fatigue properties in a cost effective way. LÄS MER
4. Laser-welded corrugated core steel sandwich bridge decks
Sammanfattning : Steel bridge decks are often used for applications when a lightweight structure is sought for. Conventional orthotropic steel decks suffers from drawbacks in several aspects, including high production costs and durability problems. LÄS MER
5. Fatigue properties of cut and welded high strength steels : Quality aspects in design and production
Sammanfattning : This doctoral thesis concerns fatigue of welded structures. Welding is one of the world’s most common joining methods and it is frequently used in several structural applications in many fields. Some examples are construction vehicles, loader cranes, trucks, busses, forestry and agricultural machines, bridges and ships. LÄS MER
