  • 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...

  • Performance of rotary regenerative heat exchanger--a numerical simulation

    Creator:
    Bae, Young Lib
    Abstract:
    This thesis examines the transient and steady-state temperature performance of a rotary regenerative heat exchanger. In contrast to previous studies on this problem, fluid flow in the circumferential direction was considered. Appropriate modeling was included to measure the effect of carry-over on the differential equations describing mass and energy conservation....

  • A computer-based design history tool

    Creator:
    Chen, Ai-hua
    Abstract:
    In current practice, design documentation often fails to support the activities of design understanding, communication, and redesign. A Design History Tool has been developed to improve current design documentation. This tool is a computerized design history that represents and plays back important information generated during the process of designing a...

    Abstract:
    This paper is a metallurgical study of the microstructure of a cobalt base hard facing alloy to determine the cause for inconsistant wear properties. Wear tests on a Stellite 6 alloy, deposited using oxyacetylene welding techniques, resulted in a wide range of weight losses. Microscopic examination has revealed the probable...

    McGinnis, Brian D.
    Abstract:
    A representation for the process of mechanical design, along with its computer implementation is presented and discussed. The representation consists of three fundamental concepts: design objects, constraints, and decisions. The design objects are the structures with which the physical artifacts of the design are described. A design object consists of...
