  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

  • A linkage finite element for nailed composite wood I-Beams and T-Beams

    Creator:
    Lee, Chyuan-shen
    Abstract:
    With current nonlinear analysis computer capabilities, this study was conducted to develop a linkage element that permits analyses of wood composite structures taking into account possible slip in the nailed joints. The finite elements chosen to represent the wood stud, plywood, gypsum and nails are described. The method as applied...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • Analysis and modeling of electrically long MESFETS and coupled schottky lines

    Creator:
    Mohammed, Ahmed Sarhan
    Abstract:
    The properties of linear active coupled lines consisting of electrically long GaAs MESFET structures are investigated for possible applications as traveling-wave broad-band amplifiers. In addition, the nonlinear coupled Schottky lines are studied for applications as voltage tunable circuit elements. The analysis of the general active asymmetric coupled transmission lines in...

  • A comparison of iterative methods for the solution of elliptic partial differential equations, particularly the neutron diffusion equation

    Creator:
    Schwinkendorf, Kevin N.
    Abstract:
    Two new concepts have been explored in solving the neutron diffusion equation in one and two dimensions. At the present time, the diffusion equation is solved using source iterations. These iterations are performed in a mathematical form which has a great deal of physical significance. Specifically, the neutron production term...

  • 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...

    Abstract:
    The objective of this study is the development and verification of an analytical solution for an unsteady flow field partially occupied by a permeable structure. Flow is induced by a small amplitude incident wave train and the permeable structure may contain multilayered anisotropic but homogeneous material. The analytical solution developed...
