  1. 1. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Zhelei Jin; [2023]
    Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

  3. 2. Experimental Testing of EPS-foam

    University essay from KTH/Hållfasthetslära

    Author : Carl Göransson; Erik Arnald; [2023]
    Keywords : Solid Mechanics; EPS; Experimental testing; Hållfasthetslära; EPS; Experimentell testning;

    Abstract : The aim of this master thesis was to investigate the mechanical properties of ExpandedPolystyrene (EPS) through experimental testing. The strain was measured on thespecimen’s surface with Digital Image Correlation (DIC), in order to investigate howthe first principal strain at fracture initiation depends on the loading of the material.

  4. 3. Irradiation Embrittlement on a Core Shroud from Decommissioned BWR

    University essay from KTH/Fysik

    Author : Åsa Bjåland; [2023]
    Keywords : hardness; Vickers hardness test; ATT; yield strength; irradiation embrittlement; welds; hårdhet; Vickers hårdhetstest; ATT; sträckgräns; bestrålningsförsprödning; svetsar;

    Abstract : Irradiation embrittlement is a problematic issue for internal structures, such as acore shroud, in a light water reactor. It is characterized by decreased ductility andtoughness, and increased yield strength and hardening due to increased dislocations. READ MORE

  5. 4. Investigation of the Applicability of Fracture Mechanics for Tissue Paper

    University essay from KTH/Hållfasthetslära

    Author : Albin Boestad; [2023]
    Keywords : Tissue Papper; Fracture Mechancis; Embossing; Mjukpapper; Brottmekanik; Prägling;

    Abstract : Tissue paper is a common type of paper material and is used in a variety of products. For tissue paper, several properties are of interest, such as absorbency, softness, bulk and mechanical properties. Embossing is an operation used to apply a pattern on tissue paper. READ MORE

  6. 5. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead

    University essay from KTH/Fysik

    Author : Gabriela Lapinska; [2023]
    Keywords : Fe-10Cr-4Al; Lead; Radiation Damage; Slow Strain Rate Testing; Fe-10Cr-4Al; bly; strålskador; Slow Strain Rate Testing;

    Abstract : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. READ MORE
