  • The application of centrifugal modeling to determine ice forces on isolated circular structures

    Creator:
    Clough, Herbert F.
    Abstract:
    A test system was developed and used to investigate ice/structure interaction with centrifugal modeling. The test system was designed to perform two main functions: (1) create a uniform ice sheet, and (2) drive a model structure through the ice sheet at a constant speed. Both of these functions were required...

  • Modeling shallow-water hydrodynamics : rotations, rips, and rivers

    Creator:
    Long, Joseph W.
    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

  • Parameters affecting mechanical collisions

    Creator:
    Aum, Ho Sung
    Abstract:
    Even though the elastic deformations that occur during the impact of colliding bodies may be small in comparison to their actual dimensions, they play an important role in mechanical collisions. During the time the bodies are in contact, elastic, friction, and inertia properties combine to produce a complex variation of...

  • Development of a posture prediction model

    Creator:
    Dendamrongvit, Thidarat
    Abstract:
    Biomechanical models have been used in designing human work environments to evaluate potential risks to workers before a work environment is constructed. In order for work environments to be modeled correctly, most biomechanical models require as input, an accurate body posture of the worker. This information can be obtained by,...

  • Numerical simulations of nonlinear baroclinic instability with a spherical wave-mean flow model

    Creator:
    Wang, Chunzai
    Abstract:
    A global, multi-level, wave-mean flow model based on an approximate version of the primitive equations is developed to investigate the development of a baroclinic wave field initially confined to a single zonal wavenumber. The effects of physical processes (surface drag and thermal damping) and internal diffusion on the evolution have...

  • Rebound predictions of mechanical collisions

    Creator:
    Lai, Liang-Ju
    Abstract:
    Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...

  • Development of an ACIP pile-specific load-displacement model

    Creator:
    Adami, Nasim
    Abstract:
    Augered cast-in-place piles, also known as ACIP piles, have been used for more than seven decades in the United States and have gained in popularity due to their relatively quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring environment as compared to some other deep foundation installation...

  • The violin's sound : a mathematical exploration employing principles of continuum mechanics and numerical methods

    Creator:
    Gyde, Nina J.
    Abstract:
    This thesis explores the vibrational behavior of the main components of sound production in the violin using a continuum mechanics approach. The author provides a mathematical description of the regions in the vibrating continuum, and begins to develop a system of equations governing their behavior, focusing on the air in...
