  • Implementation and evaluation of a participating media radiation model in the TEMPEST thermal-hydraulic computer code

    Creator:
    Rector, David R.
    Abstract:
    In this work, a method for solving the differential form of the radiative transfer equation was implemented into an existing three-dimensional thermal-hydraulic computer program known as TEMPEST. The method used was the P-l approximation, where the angular distribution of the radiation intensity is represented by a truncated series of spherical...

  • Response of guyed offshore towers to stochastic loads in the presence of steady current

    Creator:
    Brynjolfsson, Sigurdur
    Abstract:
    The validity of the widely used stochastic linearization method for analysing the response of guyed towers to stochastic loads is investigated. The governing equations of a guyed tower have two main sources of nonlinearities, fluid-structure interaction and the restoring force of the cables. In this study, two models are considered....

  • 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...

  • Kinematic analysis of legged system locomotion on smooth horizontal surfaces

    Creator:
    Baek, Yoon Su
    Abstract:
    This thesis presents a model of legged locomotion in which position and velocity of body are directly controlled by positions and velocities of feet. One central relationship between foot acceleration, leg stroke and body velocity is developed. Procedures for determining all parameters of a step sequence including periods of constant...

  • Reduced order modeling of legged locomotion in the horizontal plane

    Creator:
    Wickramasuriya, Gamika Arun
    Abstract:
    Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner over complex terrain, a feat that has yet to be equaled by man-made legged robots. Recent experimental results suggest that these insects may employ a hierarchical control structure, in which locomotion performance emerges from a combination of...

  • Dynamic finite element analysis of micropolar elastic materials

    Creator:
    Kim, Jong-bum, 1960-
    Abstract:
    In granular or fibrous materials, in which the dimensions of the internal structure can be of the same order of magnitude as major flaws or holes, classical elasticity theory does not consistently provide accurate models of the large stress gradients that may develop. With the incorporation of additional rotational degrees...

  • Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

    Creator:
    Lovejoy, Steven C.
    Abstract:
    A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

  • Optimal design of traction drive continuously variable transmissions

    Creator:
    Lim, Kyoung Ho
    Abstract:
    The optimal design technique for minimum power loss in traction drive continuously variable transmissions is developed. The mathematical model is developed to evaluate the traction force and torque in traction drive contact. Kinematic analysis of general traction drive contact is conducted to find the best configuration for minimum power loss....

  • Micromechanics of heterogeneous materials under compressive loading

    Creator:
    Laird, George
    Abstract:
    In mining and mineral processing, compressive loading is often encountered during the comminution of ore bearing minerals and in the wear resistant materials used in the comminution circuit. A common thread joining many of the materials that are primarily used under compressive loading is the presence of a high modulus...

  • Structural analysis of symmetrical penstock bifurcations by the finite element method

    Creator:
    Shugar, T. A.
    Abstract:
    A need has existed for an in-depth structural analysis of penstock bifurcations because they form an integral part of hydroelectric power plants. Their geometrical complexity has prevented classical structural analysis from providing an accurate and overall picture of the stresses in the structure. Digital computers and the development of finite...
