  3. 22. The RDGT - Integration of Micromechanics and Electronics by Plasma Assisted Wafer Bonding

    Författare :Anke Sanz-Velasco; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bonding; displacement measurement; oxygen plasma; low temperature wafer bonding; capacitive detection; high resolution; CMOS compatibility; MOSFET; low impedance sensing; resonant gate transistor;

    Sammanfattning : A high-resolution capacitive sensing technique is presented in this thesis: the Resonant Double Gate Transistor (RDGT). The major advantage of the RDGT compared to "pure" capacitive sensing techniques is its low output impedance because of the direct capacitance to current conversion of the transistor. LÄS MER

    Författare :Benjamin Neding; Peter Hedström; Dmytro Orlov; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation-induced martensitic transformation; stacking fault energy; high-energy X-ray diffraction; HEXRD; high-energy X-ray diffraction microscopy; HEDM; medium Mn steel; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Austenitic stainless steels are known for their remarkable corrosion resistance and exhibit a very high ductility and toughness. They posses the face centered cubic crystal structure. LÄS MER

  7. 25. The effect of stress state in ductile failure

    Författare :Imad Barsoum; Jonas Faleskog; Viggo Tvergaard; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile failure; Rupture mechanisms; Stress triaxiality; Lode parameter; Finite element analysis; Experiments; Localization; Micromechanics; Void growth; Void coalescence; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : The industrial application of high strength steels in structural components has increased the demand on understanding the ductile failure behavior of this type of materials. In practical situations the loading experienced on components made out of these materials can be very complex, which may affect the failure behavior. LÄS MER
