    Author : Gabriele Busseti; [2019]
    Keywords : ;

    Abstract : Fatigue analysis of the printed circuit boards (PCBs) of an avionic instrument has been analyzed. The natural frequency and transmissibility has been estimated through analytical approach and finite element approach with Solid- Works and experimentally. READ MORE

  3. 2. Furnace Brazing of AlSi-coated and Uncoated 22MnB5 Steel at Austenite Temperatures

    University essay from KTH/Lättkonstruktioner

    Author : Adam Häggqvist; [2015]
    Keywords : ;

    Abstract : By continued advances in mechanical strength of press hardened boron alloyed steel (22MnB5) weight savings can be achieved by the use of less material. However, with reduced material thickness stiffness problems such as buckling arises and the high strength of the material can’t fully be taken advantage of. READ MORE
