1. 11. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : William Tönnberg; [2022]
   Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

   Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

3. 12. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

   University essay from KTH/Materialvetenskap

   Author : Hagen Christian Hagens; [2022]
   Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

   Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

4. 13. Value of CO2 neutrality for sustainable engineering steel: A case study of Ovako AB

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Erik Larsson; Filip Smith; [2022]
   Keywords : Automotive; Battery electric vehicle; Bearing; Blast furnace; Carbon border adjustment mechanism; Carbon dioxide; Electric arc furnace; Emissions trading system; Engineering steel; Green steel; Greenhouse gas; Innovation; Internal combustion engine; Life cycle analysis; Mining; Paris agreement; Science based target initiative; Steel; Sustainability; Sustainable steel; Triple bottom line;

   Abstract : Steel production is today one of the most CO2-demanding activities and causes 8% of the global emissions of GHG. It is crucial for the industry to reduce its emissions radically in order to be in line with the goals of the Paris Agreement and the Science-Based Target initiative. READ MORE

5. 14. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

   University essay from KTH/Betongbyggnad

   Author : David Andersson; [2022]
   Keywords : Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

   Abstract : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.

6. 15. Structural strengthening and sustainability improvements of existing buildings – A case study

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Pardis Niknafs; [2022]
   Keywords : Building retrofit; structural strengthening; energy efficiency; environmental impact; integrated and sustainable intervention; cross-laminated timber; life cycle assessment;

   Abstract : In Sweden, a large share of residential buildings was built more than 50 years ago. Consequently, old materials, poor maintenance, and corrosion can affect the structural performance of these buildings. Additionally, these buildings do not meet the latest energy efficiency and Eurocode regulations. READ MORE
