    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Majed Alsmail; Baqer Rubaij; [2023]
    Nyckelord :sandwich elements; thin concrete slabs; outer concrete layer; anchoring; anchoring systems; granular rupture in outer layer; anchor pull-out; adhesion; outer layer failure; loads; reinforcement; recesses; sandwichelement; tunna betongskivor; yttre betongskiva; förankring; förankringssystem; konbrott i yttre skivan; bygel utdrag; vidhäftning; brott i ytterskiva; belastningar; armering; ursparningar;

    Sammanfattning : As part of the work in this project, a literature review is conducted to determine the optimal thickness of the outer concrete layer in prefabricated concrete sandwich elements. These elements are used as exterior walls in buildings and consist of a load-bearing inner concrete layer, an intermediate insulation layer, and an outer concrete layer that forms the building's facade.

  3. 2. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Yusuf Qasem; Younes Chraibi Ottosson; [2022]
    Nyckelord :Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

    Sammanfattning : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

  4. 3. Minska styvheten och öka stickbarheten för pappersgarn tvinnat med viskosgarn

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Tiffany Min Adelsten; Sevala Gakic; [2022]
    Nyckelord :Paper yarn; tensile strength; stiffness; Pappersgarn; draghållfasthet; styvhet;

    Sammanfattning : För att nå de Globala målen 2030 kommer vi som samhälle att behöva minska vårt globala ekologiska fotavtryck avsevärt. Textilbranschen står idag för en betydande del av detta ekologiska fotavtryck både genom markanvändning, klimatpåverkande utsläpp, förorening av mark och vatten med mera. LÄS MER

  5. 4. The Identification of Collagen Failure in Vascular Tissue

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Kathryn Dennisson; Nicole Namousi; [2021]
    Nyckelord :;

    Sammanfattning : Aortic diseases are a common and fatal health issue, regarding various conditions targeting the aorta. The arterial wall consists of two proteins; collagen and elastin (fibers), and they will contribute to the elasticity and strength of the wall. LÄS MER

  7. 5. Slow strain rate testing of welded copper

    Master-uppsats, KTH/Materialvetenskap

    Författare :Kirti Teja Pasupuleti; [2013]
    Nyckelord :copper canister; friction stir welding; slow strain rates; creep test; knock-mecking model;

    Sammanfattning : In Sweden spent nuclear fuel is planned to be placed 500 m down in the bedrock. The spent nuclear fuel will be contained in copper canisters. The reason behind the selection of copper is its thermodynamic stability against corrosion in the depository. The copper will be exposed to mechanical loading and will be plastically deformed due to creep. LÄS MER
