  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

  4. 3. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Author : Venkataramanan Mohandass; [2019]
    Keywords : Alloy 718; additive manufacturing; electron beam-powder bed fusion; surface engineering; shot peening; high temperature corrosion;

    Abstract : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. READ MORE

  5. 4. Modeling and Analysis of the Shot Peening Process : a Study of the Residual Stresses in an Insert using the Finite Element Method

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Hamid Torkaman; [2018]
    Keywords : Shot peening; Residual stresses; Cutting tool inserts; Post-coating treatment; Coated cemented carbide;

    Abstract : Cutting tool inserts are often coated with thin layers either through chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes. In order to have a better wear resistance cutting tools are mostly subjected to post-coating treatment processes. READ MORE

  6. 5. Methods to create compressive stress in high strength steel components

    University essay from

    Author : Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
    Keywords : residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

    Abstract : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.
