  1. 1. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    University essay from Lunds universitet/Materialteknik

    Author : Daniel Nesic; [2022]
    Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE

  3. 2. Alloy adaptation towards accepting higher amounts of secondary material

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Nikhil Itagi; Shubham Kadam; [2022]
    Keywords : Aluman-16; Phase diagram; Phases; Microstructure; ThermoCalc; Intermetallic; Fractography.;

    Abstract : The work presented aims to find microstructure and mechanical properties after remelting of aluman-16 alloy by using high pressure die casting (HPDC). Alloy has been casted with specific composition. The alumna-16 alloy has been casted in 2 different composition of different Si content of 0.22% and 0. READ MORE

  4. 3. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    University essay from Jönköping University/Tekniska Högskolan

    Author : Max Holmberg; Pontus Sundberg; [2022]
    Keywords : Aluminium Alloy A205;

    Abstract : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. READ MORE

  5. 4. Fatigue properties of Laser Powder Bed Fusion (LPBF) built 21-6-9 stainless stee

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Jayanth Krishna; [2021]
    Keywords : stainless steels; LPBF; Fatigue; 21-6-9;

    Abstract : Fatigue performance is one of the important mechanical properties which is hindering some of the additive manufacturing build structures. The main objective of this study is to investigate the fatigue life dependence of the 21-6-9 austenitic stainless-steel build using the laser powder bed fusion (LPBF) technique. READ MORE

  6. 5. Life and fracture in very high cycle fatigue of a high strength steel

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

    Author : Daniel Karlsson; [2021]
    Keywords : Very high cycle fatigue; VHCF; Fractography; Fine granular area; FGA; High strength tool steel; Ultrasonic testing equipment;

    Abstract : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. READ MORE
