1. Ultimate and Residual Strength Assessment of Ship Structures
Sammanfattning : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. LÄS MER
2. Dendritic morphology and ultimate tensile strength of pearlitic lamellar graphite iron
Sammanfattning : The continued development, of cylinder blocks and cylinder heads for heavy truck engines that are made of lamellar graphite iron (LGI) is focused on achieving high ultimate tensile strength (UTS) whilst conforming to environmental regulations. The purpose of this work is to further improve the tensile strength as well as the predictive engineering tools for optimization of LGI aimed to enhance the efforts for producing lighter and sustainable components without sacrificing performance.

3. Shrinkage and Related Properties of Alkali-Activated Binders Based on High MgO Blast Furnace Slag
Sammanfattning : Concrete is the second most used material in the world just after water. A drawback is that it is mostly based on Portland cement, which has an extremely high carbon footprint reaching a staggering 900 kg/tonne. The carbon dioxide emissions related to the production of the Portland cement accounts for nearly 8 % of the global total. LÄS MER
4. 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.

5. Stress-laminated-timber bridge decks subjected to ultimate loads
Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER
