  • Rebound predictions for elastic collisions

    Creator:
    Liu, Pao-pao
    Abstract:
    In this paper, a numerical method is used to predict the response of an elastic body during a collision in which both normal and tangential impulses are important. Results are compared with those from simplified prediction procedures, which stem from the assumptions that the energy-returning capacity of the normal deformation...

  • Mechanical properties of Nb-Ti composite superconducting wires

    Creator:
    Liu, He
    Abstract:
    Mechanical properties of Nb-Ti composite superconducting wires were tested at room temperature. The results were analysed using simple composite theory, the rule of mixtures. The objective is to predict the mechanical properties of Nb-Ti superconducting composite wires as a function of volume ratio and geometry of the components, the composite...

  • Predicting rebound of planar elastic collisions

    Creator:
    Cruz-Conde Gret, Raphaël
    Abstract:
    Impact is a large and complex field. It embraces both structures as simple as a nail, and more complex systems, such as a car collision. A central feature of impact theory is finding the dependence between the velocities before and after impact. The transformation law of the velocities in an...

  • 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...

  • An analytical model for fatigue crack propagation

    Creator:
    Anderson, James L.
    Abstract:
    Beginning with the basic equations from the theory of elasticity and employing a model of crack propagation based on the concept of a constant plastic energy absorption per unti of crack extension, the commonly accepted power law of fatigue crack propagation was derived. This derivation uses an extension of the...

  • Laminate mixing in microscale fractal-like merging channel networks

    Creator:
    Enfield, Kent E.
    Abstract:
    A two-dimensional model was developed to predict concentration profiles from passive, laminar mixing of concentration layers formed in a fractal-like merging channel network. Both flat and parabolic velocity profiles were used in the model. A physical experiment was used to confirm the results of the model. Concentration profiles were acquired...

  • Analysis of a wood-fueled trimburner system for use in a combined-cycle, wood-fired power plant

    Creator:
    Stephenson, Jerry D.
    Abstract:
    This report investigates the use of wood to fuel a trimburner incorporated in a combined-cycle, biomass-fired power plant. The term "trimburner" applies to a ductburner which is designed to boost the temperature of the air stream entering the gas turbine. The work presented here is part of a larger biomass...

  • 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...
