  1. 1. Modelling and Simulation of Hydrogen Diffusion in High Strength Steel

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Vikas Vineeth Seru; Venkata Ramana Murthy Polinati; [2021]
    Nyckelord :Coupled temperature displacement; finite element software; high strength steel; hydrogen diffusion; material properties.;

    Sammanfattning : This research is about modelling and simulation of how the hydrogen diffuses in high strength steels. The hydrogen diffusion in the material was examined by using finite element software with the help of material properties and some existing data. LÄS MER

  3. 2. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Dahman Ismail; Alexis Andrei; [2020]
    Nyckelord :finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Sammanfattning : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. LÄS MER

  4. 3. Charge transport in a Hubbard-Holstein junction: Preliminary results from a DFT approach.

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Eric Ceccarelli; [2019]
    Nyckelord :Density functional theory; DFT; Hubbard-Holstein; Hubbard-Holstein model; HH; Quantum transport; Physics and Astronomy;

    Sammanfattning : Many-body systems are extremely complicated to describe due to mutual interactions between the constituent particles. This is for example the case of systems with electron-electron (e-e) and electron-phonon (e-ph) interactions. LÄS MER

  5. 4. HPDC Die design for Additive Manufacturing : Simulation and Comparison of Thermal Stresses in HPDC die designed for Additive Manufacture

    Master-uppsats, Högskolan i Jönköping/JTH, Industriell produktutveckling, produktion och design

    Författare :Ambareeksh Tharayil Pradeep; Mohammadali Baradaran; [2019]
    Nyckelord :High Pressure Die Casting; Additive Manufacturing; Finite Elements Analysis;

    Sammanfattning : Additive manufacturing has a great potential to benefit die manufacture by shortening the lead time considerably and lifting the limitations on design complexity imposed by conventional manufacturing techniques. However, AM has its own requirements that together are known as Design for Additive Manufacturing and account for the process limitations. LÄS MER

  7. 5. Novel micromechanical bulk acoustic wave resonator sensing concepts for advanced atomic force microscopy

    Master-uppsats, KTH/Mikro- och nanosystemteknik

    Författare :Stefan Wagner; [2012]
    Nyckelord :;

    Sammanfattning : This thesis investigates novel concepts of micromechanical bulk acoustic wave sensors for advanced atomic force microscopy (AFM), using micromachined silicon resonators, which are analyzed with regard to their performance as compared to conventional AFM sensors. Conventional AFM systems use a cantilever resonator for sensing the surface forces of the sample. LÄS MER
