    Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER

  2. 2. Mechanical characterization and modelling of iron ore pellets

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Sammanfattning : Transportation and storage are important parts in the process chain for producers of iron ore pellets. Knowledge and optimization of these processes are very important for further efficiency progress and increased product quality. LÄS MER

  3. 3. Impact damping and airplane towing : two studies of the response of solid bodies to transient loads

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Carlos Matuk; [1982]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The impact of a linearly elastic hammer on a linearly viscoelastic plate is the first problem considered in this thesis. The results, obtained by using the Laplace transformation method, can be used in the design of impact protection devices. LÄS MER

  4. 4. Modeling of structural integrity of aged low alloy steels using non-local mechanics

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Magnus Boåsen; Pål Efsing; Jacques Besson; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : Ageing of low alloy steels affects the structural integrity assessment as it most commonly causes embrittlement and a hardening of the material. This is due to theevolution of the microstructure during operation in the specific application. LÄS MER

  5. 5. Coupled vibrations in horizontal and vertical rotor-bearings systems

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jean-Claude Luneno; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology - Engineering mechanics; Teknikvetenskap - Teknisk mekanik; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : For dynamical systems having several degrees of freedom, motion in one direction can induce motion in the other and/or vice versa. This means that there is a certain coupling between these two motions. Coupling can in some cases be a source of instability that causes self-excited vibrations in rotating machinery. LÄS MER
