    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydraulik; vakuumteknik; vibrationer; akustik; Maskinteknik; hydraulics; Mechanical engineering; friction; FEM; numerical modelling; continuum mechanics; fatigue loading; powder compaction; vacuum technology; vibration and acoustic engineering;

    Sammanfattning : This thesis addresses powder manufactured (P/M) components, with special attention to the compaction process and to the sensitivity to damage accumulation due to fatigue within powder compacted specimens. Three dimensional simulations of the compaction process have been performed, using an explicit dynamic dilatant finite strain finite element code supplemented with the effects from contact friction within the die, modelled by Coulomb friction.

  3. 3. TV holography and shearography in experimental mechanics

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Henrik O. Saldner; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : TV holography is an optical non-contacting whole field technique to measure deformation. Names as ESPI or Electronic speckle pattern interferometry, Electro-optic holography and Electronic holography are commonly used for this real-time video based interferometric technique. Shearography has become an important tool in non destructive testing. LÄS MER
