  1. 21. Characterization of uranium oxide powders and sinterability

    University essay from KTH/Kemiteknik

    Author : Joakim Ceder; [2021]
    Keywords : uranium dioxide; sinterability; reduction; pore former; chemical activity; urandioxid; sintringsaktivitet; reduktion; porbildare; kemisk aktivitet;

    Abstract : Uranoxid (UOx) är ett energitätt material som ofta används i kärnbränsle. UOx-pulver pressas och sintras för att tillverka urandioxidkutsar som förs in i bränslestavar. Stavarna monteras slutligen ihop till ett bränsleknippe. Tillverkningsprocessens stabilitet och förutsägbarhet är viktiga. READ MORE

  5. 24. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage

    University essay from KTH/Betongbyggnad

    Author : Sidra Akbar; Mathias Carlie; [2021]
    Keywords : Balanced cantilever bridges; box girder cross-section; concrete; non-uniform creep and shrinkage; Bažant’s B4 model; Eurocode 2; long-term deformations; finite element analysis; Freivorbau broar; lådtvärsnitt; betong; ojämnkrypningoch krympning; BažantsB4 modell; Eurokod 2; långtidsdeformationer; finita element analys;

    Abstract : Balanced cantilever bridges have historically experienced excessive deformations. Previous researchsuggeststhat the cause may be due to differential thickness in the box girder cross-section and underestimation of creep and shrinkage. READ MORE

  6. 25. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Niclas Elfving; Joel Sunesson; [2021]
    Keywords : Concrete; Creep; Segmentally constructed; Prestressing; Post-tensioning; Viscoelastic; Eurocode; Finite Element; Shell elements; Beam elements; Time-dependant; Steel relaxation.; Technology and Engineering;

    Abstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE
