  • Large-strain softening of aluminum in shear at elevated temperature

    Creator:
    Alhajeri, Saleh N.
    Abstract:
    Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...

  • Elastodynamic analysis of a propagating finite crack in a micropolar elastic solid

    Creator:
    Han, Seog-young
    Abstract:
    A dynamic propagation of a finite crack of opening mode in a micropolar elastic solid was investigated. By using an integral transform method, a pair of twodimensional singular integral equations governing stress and couple stress was formulated in terms of the displacement transverse to the crack, macro- and microrotations, and...

  • A study of buoyant backflow in vertical injection lines

    Creator:
    King, John Barry
    Abstract:
    In the event of a small break loss of coolant accident (SBLOCA) in a nuclear reactor, cold fluid is injected through the reactor system high pressure injector to compensate for the coolant loss. When this flow rate is less than a critical value, however, the hot fluid in the cold...

    Creator:
    Stevens, Owen L.
    Abstract:
    The Oregon State University (OSU) Radiation Center (RC) is the location of a one quarter scale model of the Westinghouse Electric Corporation advanced light-water nuclear reactor design called the AP-600. The full scale AP-600 is a 600 megawatt electric nuclear power plant that incorporates unique passive systems to perform the...

  • A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

    Creator:
    Park, Heeyong
    Abstract:
    The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

  • Thermal and seismic analysis of piping systems using classical methods

    Creator:
    Nisargand, Arun L.
    Abstract:
    "Piping Design and Engineering" first published in 1963 by Grinnell, Co. is widely used by engineers to perform approximate thermal stress analysis of high-temperature piping systems. The text consists of numerical constants to calculate end reactions and maximum bending stresses in a variety of piping configurations from known properties of...

  • Quantification of total and plastic 3D strain fields within micro-damaged polyurethane foam

    Creator:
    Sutton, Matthew T.
    Abstract:
    Local material damage that occurs within cellular solids, such as polymer foams and trabecular bone, and precedes local fractures of the cell struts or walls is called micro-damage. The accumulation of micro-damage within cellular solids is often undesirable, although it is thought to be vital to the development and health...

  • Experimental investigation of merging buoyant jets in a crossflow

    Creator:
    Gregorič, Miroslav
    Abstract:
    Merging isothermal buoyant jets in a crossflow were investigated experimentally. Jets of salt water were discharged from a constant head tank into the stagnant tap water. A crossflow was simulated by towing the discharge ports through the receiving water at desired speeds. Visualization of the jet cross-sections produced by a...
