  1. 21. Weight reduction of radar platform : Concept development, analysis and evaluation

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Lucas Parpis; [2017]
    Nyckelord :;

    Sammanfattning : The aim of this master thesis has been to produce and evaluate a set of lightweight concepts for a radar system mounting platform. The evaluation aims to cover relevant aspects specifically regarding the Saab Arthur weapon locating system, as well as the Saab Giraffe 4A multifunctional radar system. LÄS MER

  3. 22. Numerical analysis of connection in wind turbine rotor blade

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Albin Ingmarsson; [2017]
    Nyckelord :fibre reinforced composite; truss structure; lightweight; renewable energy; wind turbines; rotor blades; adhesive; finite element method; Technology and Engineering;

    Sammanfattning : A globally growing population, an increased energy consumption and growing environmental awareness have made the interest for renewable energy sources, such as wind power, higher. As a result of the increased demand the need for new and improved technologies have increased. LÄS MER

  4. 23. Shape Distortion Analysis of Self-Reinforced Poly(ethylene terephthalate) Composites : The PETrifying reality!

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Calle Eliasson; [2016]
    Nyckelord :;

    Sammanfattning : Composite components with a V-shaped geometry have been manufactured through compression moulding of fabrics based on self-reinforced poly(ethylene terephthalate). The fabrics were subjected to a set of predetermined degrees of stretching during manufacturing with the intent to investigate its effects on shape distortions in terms of spring-in and warping.

  5. 24. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Adam Jansson; [2016]
    Nyckelord :warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Sammanfattning : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. LÄS MER

  7. 25. Multi-axial damage and failure models for thick composite lugs under static and cyclic loading

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Jean-Michel Rameau; [2015]
    Nyckelord :fibre-reinforced composite; multi-axial; quasistatic; fatigue; damage; Puck’s criterion; Faserverbundwerksto˙; mehrachsige Span-nung; statische Berechnung; Ermüdung; Puck-Kriterium; Schaden;

    Sammanfattning : The thesis deals with quasi-static and fatigue simulations of thick composite lugs subjected to three-dimensional stress states. This includes damage prediction of hybrid laminates made of GRFP and CRFP containing unidirectional and woven fabric plies. LÄS MER
