  1. 1. Investigation of Non-Metallic Inclusions in Inconel 718 by Using Conventional Cross-Sectioned (CS) Method and Experimental Extraction Metal-Surfaced (MS) Method

    University essay from KTH/Materialvetenskap

    Author : Mehreen Baig; [2022]
    Keywords : ;

    Abstract : Inconel 718 is a nickel-based alloy, predominantly used in the oil and gas industry, in aircraft engines as well as in gas turbine engines. It provides exceptional properties like high strength, creep resistance, corrosion resistance and long fatigue life at high temperatures as well as in cryogenic environments. READ MORE

  3. 2. 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

    Abstract : Better Shelter is a company, developing and providing module housing units for refugees in crisis areas. These module housing units are kept in place against wind and harsh conditions by 10 ground anchors, that are buried and tied to the frame. READ MORE

  5. 4. Fatigue analysis of welded joints in a forestry machine : Utilizing the notch stress concept

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT); Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Martin Nyström; Tainan Pantano Tomaz; [2015]
    Keywords : Weld; Fatigue; Finite Element Method; Hot-Spot Method; Notch Stress Method; Structural Dynamics; Forestry Crane; Svets; Utmattningslivslängd; Finita-elementmetoden; Hot-spot; Notch-stress; Notch-spänning; Strukturdynamik; Skogsmaskinskran;

    Abstract : Welding is one of the most applied technics in the world for joining steel. Welds are liable to the phenomenon of fatigue, which is, primarily, the formation of a crack and consequently reduction of strength due to the action of time varying loads. Fatigue is one of the main causes of failure in steel structures. READ MORE

  6. 5. Accuracy Study in Predicting Fatigue Life for a Welding Joint.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Emma Fredriksson; [2015]
    Keywords : ;

    Abstract : This thesis describes a comparative study between two calculations methods for life estimates of a welding joint. The two studied methods are the Effective Notch and Linear Elastic Fracture Mechanics (LEFM). The effective notch method is today used at GKN and gives an equitable accuracy relative the work effort for the method. READ MORE
