1. 11. Finite Element Modeling of Installation Effects of Soil-Cement Columns

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Anne Holtmeier; [2022]
   Keywords : Deep Mixing; Soil Stabilization; Installation; Finite Element Method; PLAXIS;

   Abstract : Since the 1970's deep mixing columns have been widely used all over the world to improve the performance of soft soil in regard to bearing capacity or deformation behaviour. They are installed by mixing a binding agent, e.g. cement, in situ with the soil. READ MORE

3. 12. 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

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. Mechanical properties of WE43 : Finding optimized process parameters using PBF-LB for enhanced properties of the magnesium alloy

   University essay from Uppsala universitet/Institutionen för materialvetenskap

   Author : Fanny Saarela; Fanny Sandblad; [2022]
   Keywords : biomedical engineering; materials science; additive manufacturing; powder bed fusion laser beam; PBF-LB; magnesium; magnesium alloys; WE43; mechanical properties; scan strategy; layer rotation; build direction; build orientation;

   Abstract : When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. READ MORE

6. 15. 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.
