  1. 1. Evaluation of pretension losses in heated screw joint

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Joel Svensson; [2022]
    Keywords : screw joint; clamping force; thermal load;

    Abstract : The heated flow within the silencers of heavy transport vehicles can easily reach temperatures of hundreds of degrees Celsius. The thermal loads can cause problems for certain components on a silencer. READ MORE

  3. 2. Qualification of a Physical Model of Cladding Creep During Dry Storage of Spent Nuclear Fuel

    University essay from KTH/Fysik

    Author : Robin Andersson; [2022]
    Keywords : Dry Storage; Thermal Creep; Zircaloy-4; Pellet-Cladding Interaction; Torrt Förvar; Termisk Krypning; Zircaloy-4; Kuts-Kapsling Interaktion;

    Abstract : In dry interim storage of spent nuclear fuel, thermal creep is one of the major threats to the fuel cladding integrity due to the constant decay heat generation from the fission products and minor actinides in the fuel, and the increase in fuel rod internal pressure which is present after burnup. Plenty of research has been done on either empty cladding tubes irradiated in a research reactor, or on spent fuel that is defueled prior to the examination. READ MORE

  4. 3. Boxtemperaturens effekt på antalet avvanda smågrisar : en fältstudie under svenska förhållanden

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Fay Wharton; [2021]
    Keywords : Gris; sugga; grisning; kullnummer; box; temperatur; avvanda smågrisar;

    Abstract : Att maximera antalet avvanda smågrisar per sugga har blivit ett viktigt mål inom dagens svenska grisproduktion, men fortsatt stora problem med hög smågrisdödlighet utgör en utmaning för producenterna och har negativa konsekvenser för djurvälfärden. Temperatur är en miljöfaktor som kan inverka på smågrisdödligheten och som visat sig kunna variera mellan boxar i samma stall, men få studier har undersökt omgivningstemperaturens effekt på suggornas prestation under svenska produktionsförhållanden.

  5. 4. Basic Creep of Young Concrete - Sensitivity in the Evaluation Method

    University essay from KTH/Betongbyggnad

    Author : Benar Ekmat; Natalea Hermes; [2019]
    Keywords : thermal cracking; young concrete; creep; Linear Logarithmic Model; temperature development; average strain; sensitivity.; Temperatursprickor; ung betong; krypning; Linjär Logaritmisk Modell; temperaturutveckling; töjning; känslighet.;

    Abstract : Creep is defined as deformation that takes place under constant load after an initial elastic response. This thesis focuses on a material property problem area that concerns stress analysis. Focus is on stress development considering creep deformations occurring when a concrete structure is under load, i.e. READ MORE

  6. 5. Polymer Aging Mechanics : An investigation on a Thermoset Polymer used in the Exterior Structure of a Heavy-duty Vehicle

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Basil Abu-Ragheef; [2019]
    Keywords : polyDicyclopentadiene; aging; thermosets; fatigue; mechanical properties; thermal fatigue; digital image correlation; viscoelasticity; polymer degradation; thermo-oxidation; photo-oxidation;

    Abstract : The use of plastic materials in the design of vehicle components is primarily driven by the need for vehicle weight and cost reduction. Additionally, these materials give design engineers freedom in creating appealing exterior designs. READ MORE
