  1. 11. 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

  3. 12. Survival of Zirconia Implants: A Systematic Review and Meta-Analysis

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Parvin Mohseni; Ahmad Soufi; [2023]
    Keywords : dental implant; failure; implant; meta-analysis oral implant; systematic review; zirconia implants;

    Abstract : Aim To assess the clinical outcomes of zirconia implants, namely survival rate and the prevalence of fracture, based on a systematic review of the literature. Material and method An electronic search was conducted in three databases (PubMed, Web of Science, Science Direct), last updated in October 2022. READ MORE

  4. 13. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

    University essay from Lunds universitet/Industriell Produktion

    Author : Cornelis Botermans; [2023]
    Keywords : Technology and Engineering;

    Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

  5. 14. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Erik Stålbrand; [2023]
    Keywords : Solid Mechanics; Material Modelling; Damage Modelling; Sheet Metal Damage; Punching Simulation; Forming Simulation; Heat Exchanger; Technology and Engineering;

    Abstract : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

  6. 15. 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
