  • Indentation hardness of Douglas fir and Western hemlock lumber related to density

    Creator:
    Corder, Stanley E.
    Abstract:
    Indentation hardness tests were made on sections of 211 pieces of Douglas fir and 208 pieces of Western hemlock at a moisture content of about 11 percent. Specific gravity and visual-density evaluations were also determined. Correlation coefficients for linear regression of density, as measured by specific gravity, on average standard...

  • The effect of alpha phase morphology on the impact energy of commercial purity titanium

    Creator:
    York, James Michael
    Abstract:
    Samples of commercial purity titanium were heat treated above the beta transformation temperature and within the two phase alpha-beta phase field, followed by cooling at varying rates. Testing of the samples in tension and by instrumented impact indicated that some strengthening could be imparted by these heat treatments, although at...

  • Effects of selected minor alloying additions on the structure deformation characteristics of beryllium

    Creator:
    Dooley, George Joseph, III
    Abstract:
    Solid solution alloying was employed in an attempt to produce some relatively ductile form of beryllium. If the c/a ratio could be significantly altered, it was felt new or different slip systems could be activated. The following elements were selected on the basis of atomic size, melting point, crystal structure...

  • Photonic Sintering of Nanoparticle Inks : Experimental Characterization, Computational Modeling and System Design for Additive Manufacturing

    Creator:
    MacNeill, William D.
    Abstract:
    Photonic sintering of nanoparticles is a relatively new process for sintering of nanoparticles, deposited on a substrate, into functional solid structures. The working principle of this process is the incidence of large-area broad-spectrum light onto deposited nanoparticles, which results in heat generation in the nanoparticles and their subsequent densification. Key...

  • Dynamic modeling of a refrigerant boiler for power applications

    Creator:
    Curry, Thomas Haitsch
    Abstract:
    A dynamic model of a refrigerant boiler has been produced by the use of distributed parameter modeling techniques. A number of elementary cases were studied and were used as an aid in the final model formulation. Modeling using distributed parameters employed the use of mesh equations which were then reorganized...

  • Discrete-time explicit model reference adaptive control for robotic manipulators

    Creator:
    Yuh, Junku
    Abstract:
    In this dissertation a direct approach to discrete-time model reference adaptive control (MRAC) based on hyperstability theory is proposed to control industrial robotic manipulators. For industrial robots and manipulators, which usually have highly nonlinear and complex dynamic equations and often have unknown inertia characteristics, it is very difficult to achieve...

  • Mechanics of Nb-Ti superconducting composites

    Creator:
    Guo, Zhiqiang
    Abstract:
    Mechanical behavior of Nb-Ti superconducting composites with copper matrices have been studied experimentally and theoretically. Experimental work includes extensive measurements of Cu/Nb-Ti composite system. Techniques for fine fiber testing and composite wire measurement have been developed. Experimental parameters examined in this research include geometry, hardness, Young's modulus, Poisson's ratio, yield...

  • Wind turbulence input model for horizontal axis wind turbines

    Creator:
    Lin, Shuh-ren
    Abstract:
    In order to estimate wind turbine residL2;characteristics in the presence of atmospheric turbulence, the important atmospheric sources for the force excitations felt by the wind turbine system must be identified and characterized. The goal of this research is to develop the wind turbulence input model for horizontal axis wind turbines....

  • Thermal and seismic analysis of piping systems using classical methods

    Creator:
    Nisargand, Arun L.
    Abstract:
    "Piping Design and Engineering" first published in 1963 by Grinnell, Co. is widely used by engineers to perform approximate thermal stress analysis of high-temperature piping systems. The text consists of numerical constants to calculate end reactions and maximum bending stresses in a variety of piping configurations from known properties of...
