  1. 21. Simulations of experimental crack development in ceramic material with notched specimen

    University essay from KTH/Hållfasthetslära

    Author : Clas Dahlin; [2022]
    Keywords : Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Abstract : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. READ MORE

  3. 22. Effect of Cement Type on Zirconia and Metal-Ceramic Tooth-Supported Crowns – A Retrospective Journal Survey

    University essay from Umeå universitet/Tandläkarutbildning

    Author : Jennifer Nilsson; Mikael Wedin; [2022]
    Keywords : dentistry; prosthodontics; crown; cement; zirconia; porcelain-fused-to-metal;

    Abstract : Background: The golden standard for single unit crowns has for long been porcelain fused to metal (PFM). However, demands for improved esthetic materials has driven the development of zirconia which has increased in popularity due to its eminent mechanical and esthetic properties. READ MORE

  4. 23. Material analysis for a rotating inlet valve : Sliding contact in an oil-free super-critical steam environment

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johan Samuelsson; [2022]
    Keywords : Mechanical carbon; graphite; carbon graphite; zirconia; steam engine; steam; tribology; friction; wear; stellite; nitronic 60; antimony; carbon; Ni-resist cast iron; waste heat recovery; rotating inlet valve; valve; Mekaniskt kol; gafit; ångmotor; ånga; tribologi; friktion; nötning; gjutjärn; roterande inloppsventil; ventil;

    Abstract : In this thesis, the aim is to study possible tribo-materials for a rotating inlet valve and to find a suitable material combination for the contact. The valve is part of a modern oil-free and high temperature steam engine. Systematic material selection together with tribological tests and wear analyses are performed. READ MORE

  5. 24. The Impact of Water Addition on the Fracture Toughness of Pre-cast Refractory Materials

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Paulina Lindblad; [2022]
    Keywords : refractory materials; pre-cast elements; ceramics; fracture toughness; water addition; porosity; ceramic vortex finder;

    Abstract : A ceramic vortex finder (CVF) is the central pipe (gas outlet) of a gas cyclone, which is an important structural component within gas cyclone separation. Its main application is within high temperature processes, within the energy and cement industry where the atmosphere is highly abrasive and corrosive. READ MORE

  6. 25. Rocks in Vogue : on material flows within electronic devices

    University essay from Konstfack/Institutionen för design, inredningsarkitektur och visuell kommunikation (DIV); Konstfack/Industridesign

    Author : Giorgia Burzio; [2021]
    Keywords : Design research; Material flows; Electronics; Energy; Battery; Care; Waste; Recycling; Craft; Critique; Landscape;

    Abstract : Landscapes have been exploited and polluted by humans in order to obtain metals. Materials are treated as commodities: extracted, used inside our devices and appliances, then discarded as useless matter. The timespan of efficiency is shortened more and more due to obsolescence, material desire and constant innovation. READ MORE
