  1. 1. Acoustic emission methods in fatigue testing

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Axel Lison Almkvist; [2015]
    Keywords : Acoustic emission; AE; grey iron; CFRP; Akustisk emission; AE; gråjärn; CFRP;

    Abstract : Acoustic emissions are small vibration pulses, elastic waves, emitted from damage processes such as crack growth inside a material. Acoustic emission (AE) is also the name of the test method in which theses emissions are recorded and analysed and the method is used in materials research and the testing and inspection of structures.

  3. 2. Thermo-mechanical fatigue of castiron for engine applications

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Niklas Collin; [2014]
    Keywords : Thermo-mechanical fatigue; TMF; CGI; LGI; fatigue; thermal strain.; Termomekanisk utmattning; TMF; CGI; LGI; termisk töjning.;

    Abstract : In an engine component the repeated start-stop cycles cause temporal and local inhomogeneous temperatures, which in turn lead to a type of low-frequency loading, plastic deformation and eventually failure due to thermo-mechanical fatigue. Simultaneously, high-frequency mechanical loading arises from the cyclic combustion pressure and from road induced vibrations. READ MORE
