  • An experimental study and a three-dimensional numerical wave basin model of solitary wave impact on a vertical cylinder

    Creator:
    Zhang, Wenbin
    Abstract:
    An experiment on solitary wave impact on a vertical cylinder was conducted in the three-dimensional wave basin at the Oregon State University Hinsdale Wave Research Laboratory. The cylinder was designed using mechanic principles and finite element analysis techniques to enable accurate measurement of horizontal force and overturning moment. Video data...

  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • Three Topics on Coastal Hazards : Propagation, Transformation, and Impact

    Creator:
    Ko, Harrison T.
    Abstract:
    An understanding of natural coastal hazards is essential for improving resilience of coastal communities. Effective management of coastal hazards relies on prediction tools and mitigation structures that have been designed to handle the dynamic coastal system. This dissertation is a collection of manuscripts that cover a diverse range of fundamental...

  • Hydrodynamic contact/impact modeling and application to ocean engineering problems

    Creator:
    Challa, Ravi
    Abstract:
    Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...

  • Fluid-structure interaction analysis with the particle finite element method

    Creator:
    Zhu, Minjie
    Abstract:
    To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

  • Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

    Creator:
    Ambauen, Spencer J.
    Abstract:
    A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...

  • Tsunami-induced Soil Instability

    Creator:
    Fischer, Rachael Marie
    Abstract:
    Recent tsunami field surveys from the 2011 Great East Japan Earthquake and Tsunami have recorded numerous examples of tsunami-induced soil instability: significant scour around foundations, foundation failure of piles, and other damage caused by liquefaction. From the observations of soil instability leading to the failure of critical coastal structures, it...
