  1. 16. Simulation of Rolling Mill to Computeand Improve Load Distribution

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

    Author : Pontus Darth; [2021]
    Keywords : Finite Element; Simulation; Hot rolling mill; SSAB; Swerim AB; Roll Spallings; Spallings; Roll Failure;

    Abstract : This master thesis was done at Swerim AB in cooperation with SSAB and the Technical University of Luleå in the purpose of preventing spalling problems in hot rolling mills. Spallings are a fatigue damage that occurs on the rolls due to extreme loads and unfavorable conditions between the rolls in a mill. READ MORE

  3. 17. Development of a method for estimation of contact fatigue life in hypoid gears

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srigiripura Sahana Vittal; [2020]
    Keywords : Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

    Abstract : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. READ MORE

  4. 18. Estimating the probability of levee failure for flood risk mapping : An application to Paglia River

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Theodora Neromylioti; [2020]
    Keywords : Levee failure; inner erosion; piping; backward erosion; seepage; probability of failure; fragility curves; time-dependent failure; hydraulic modelling; flood risk; flood inundation; HEC-RAS;

    Abstract : Climate change results to more extreme and frequent flood events that induce extra risk to flood protection structures such as levees. Thus, estimation of the probability of levee failure is of utmost importance when it comes to structural safety and flood risk assessment. READ MORE

  5. 19. FE-analysis of roller creasing of corrugated board

    University essay from KTH/Hållfasthetslära

    Author : Isak Hampel Klang; [2020]
    Keywords : ;

    Abstract : Creasing is often performed on paperboard to lower the bending stiffness in a region, making the paperboard easier to fold. Packsize AB uses rolls to crease corrugated paperboard. When using rolls for creasing double-walled corrugated paperboard in the machine direction, fracture occasionally occur on the top liner. READ MORE

  6. 20. Limiting factors in capercaillie (Tetrao urogallus) conservation

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Christer Moreira Boman; Andreas Pettersson; [2019]
    Keywords : reintroduction; conservation; capercaillie; wildlife management; population viability analysis;

    Abstract : With current extinction rates comparable with the rates of previous mass extinctions and humanities necessity of biodiversity, conservation of habitat and species should be regarded as paramount whenever planning land use. In this paper we have focused on the Western capercaillie (Tetrao urogallus) an umbrella species in Eurasian boreal and temperate forests. READ MORE
