    Stress concentrations in tensile strips with large circular holes (1972)
    Springer
    Experimental mechanics 12 (1972), S. 190-195 
    Details
    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The purpose of this investigation was to determine more accurately the stress concentrations in tensile strips having large circular holes where the ratio of the hole diameter to strip width is greater than 0.5 Results of numerical elasticity analyses are presented for ratios of hole diameter to bar width ranging from 0.10 to 0.99, and photoelastic data are presented for the range from 0.40 to 0.94. Both numerical results and photoelastic data indicate that the stress-concentration factor based on net area approaches a value of one as the ratio of hole diameter to bar width approaches a value of one.

    The Space Shuttle, fluid dynamics, and computer graphics (1986)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: Several samples are presented of CFD-generated flow ribbon images of fuel flow in the SSME. The images result from simulations of H2 flow through a design iteration of the main injector, the hot gas manifold and the fuel bowl section. The color-coded ribbons provide three-dimensional perspectives which indicate the direction and orientation of the flow and the velocity magnitude in intervals along the flow path.

    Visualizing flow in the Space Shuttle Main Engine (1985)

    Publication Date: 2019-06-28
    Description: Ongoing work is described aimed at applying advanced post-processing techniques to interpret and understand the complex flow behavior of the Space Shuttle Main Engine. The use of color graphics and powerful new engineering work stations to effectively present massive amounts of numerical data is emphasized. This combination of tools can result in better designs, faster turnaround, and more complete understanding of complex engineering systems like the Shuttle. Furthermore, it allows engineers access to the massive amounts of data generated by supercomputers and provides a more efficient coupling of man and supercomputer.

    Some advances in digital flow visualization (1987)

    Publication Date: 2019-06-28
    Description: The ability to visualize complex objects, concepts, interactions, and phenomena, to 'SEE' them in the mind's eye, has always been a fundamental component of the engineering discipline. Today, driven by increasingly demanding design requirements and an avalanche of data from powerful new computers and sophisticated experimental devices, the need to visualize data effectively is more important than ever before. This pressing need has resulted in the rapid increase in the use of computer-generated graphics in engineering. This is particularly true in the field of fluid dynamics where the internal structure of flow, not just surface or geometric effects, must be interpreted and communicated. This paper reports on several recent developments in the application of digital computer-generated graphics to engineering requirements for visualization of flow.
