  • Finite element analysis of wave interference effects between large structures

    Creator:
    Huang, Min-chih
    Abstract:
    A numerical calculation procedure for the hydrodynamic interference effects between large multiple structures interacting with linear ocean waves is presented in this study. Viscous effects are neglected and the hydrodynamic pressure forces are assumed to be inertially dominated. A finite element method which incorporates radiation boundary dampers is adopted to...

  • Interaction of water waves and deformable bodies

    Creator:
    Broderick, Laurie L.
    Abstract:
    A time-domain model was developed to predict the fluid/structure interaction of a three-dimensional deformable body in a fluid domain subject to long-crested finite amplitude waves. These nonlinear waves induce transient motion in the body. In turn, the interaction of the body with the waves modifies the wave field, causing additional...

  • Nonlinear dynamic analysis of cable and membrane structures

    Creator:
    Lo, Alain
    Abstract:
    The nonlinear dynamic analysis of cable and membrane structures is presented in this study. Attention is given to the nonlinearities arising from large displacements, from nonlinear stress-strain relationships and from nonconservative loadings. The finite element method is used to model the cables and membranes. Curvilinear geometries of the elements are...

  • Identification of structural parameters and hydrodynamic effects for forced and free vibration

    Creator:
    Kruchoski, Brian L. (Brian Louis)
    Abstract:
    Statistically-based estimation techniques are presented in this study. These techniques incorporate structural test data to improve finite element models used for dynamic analysis. Methods are developed to identify optimum values of the parameters of finite element models describing structures. The parameters which may be identified are : element area, mass...

  • Coupled response of compliant offshore platforms

    Creator:
    Young, Raymond A.
    Abstract:
    A three dimensional finite element analysis is developed which is capable of simulating the coupled static and dynamic behavior of compliant ocean structures. Nonlinearities which result from large-deflection, reduced or zero stiffness in compression, and the nonconservative fluid loading are considered. The spatial variation of fluid loading is also addressed....

  • Cable dynamics in an ocean environment

    Creator:
    Tuah, Hang
    Abstract:
    The nonlinear dynamic analysis of cable and cable-large body systems subject to both deterministic and non-deterministic loading is presented in this study. Nonlinearities occur due to large displacements, material nonlinearity, lack of stiffness in compression, and the non-conservative fluid loading. A finite element model is used to model the cable...

  • Long cables under steady ocean loads with coupled tension/torsion

    Creator:
    Simpson, Randall C.
    Abstract:
    Cables used in the ocean are often constructed of helically wound wires or strands. Tension in the cable induces torque and/or rotation about its longitudinal axis. A method is presented to determine the tension, torque, location and angular orientation of points on the cable centerline, using a shooting method algorithm...

  • Finite element analysis of wave-structure interactions in the time domain

    Creator:
    Lee, Jaw-fang
    Abstract:
    The time-domain simulation of wave-structure interactions using the finite element method is presented in this study. Combined initial and boundary value problems for diffraction and radiation of waves by large structures are posed. Linearized free surface boundary conditions are used, but motions of the structural boundaries compared to the wave...
