  1. 21. Assessment of creep damage in Fe-Ni-Cr alloys

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Frans Sorsh; [2019]
    Keywords : ;

    Abstract : It is only a matter of time before components working in high temperature environments fail due to creep. Design for creep is therefore of vital importance to maximize the lifetime of components and reduce costs that may arise from maintenance and replacement of components. READ MORE

  2. 22. Optimization of case-hardening depth for small gears

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Johannes Nyman; [2019]
    Keywords : ;

    Abstract : The optimization of case hardening depth for small gears was investigated with the use of Abaqus and the subroutine DANTE to simulate the formation of the microstructural phases, resulting in residual stresses and increased hardness. This was done with a step wise increment of the carburizing time, resulting in a theoretical maximum for compressive residual stresses at the surface. READ MORE

  3. 23. Static and dynamic characterization of elastomers by a modified hardness test

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

    Author : Omar Chouman; [2019]
    Keywords : Rubber; elastomer; modified hardness test; dynamic and static characterization; damping; dynamic shear modulus; hyperelastic material; hyperelastic constants; finite element method; FEM; FEA; Abaqus; Volvo Cars; Technology and Engineering;

    Abstract : Today rubber can be found in many different applications, such as vibration dampers, tyres, clothes and gaskets. Two different types of rubbers are used today, namely the natural rubber and synthetic rubber. Natural rubber is made of a milky substance called latex, which is obtained from special trees found in tropical countries. READ MORE

  4. 24. Wearable Sensors in Prosthetic Socket

    University essay from KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Author : Ahmed Moustafa; Johan Danmo; [2019]
    Keywords : ;

    Abstract : There is a great interest among researchers and clinicians to monitor pressure distributions within prosthetic sockets. Such an application may allow the assessment of the user's comfort and identify problematic areas inside the socket. The sensor that is used within such an application is the Force Sensitive Resistor (FSR). READ MORE

  5. 25. Effect of Process Parameters on Contour Properties in Inconel 718 Structures Fabricated by Electron Beam Melting

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Karthik Vaidyalingam Arumugam; [2019]
    Keywords : Process Parameters; Contour Properties; Inconel 718; Electron Beam melting;

    Abstract : Additive Manufacturing (AM), commonly known as 3D printing is a production method that utilises repeated addition of layers in order to produce a final shape. AM utilises less raw material and does not have drawbacks such as tool wear and material wastage as seen in conventional machining. READ MORE
