Download or read book The Correlation of Nondestructive Test Techniques with the Fracture Behavior of ATJ S Graphite written by W. L. Shelton and published by . This book was released on 1972 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selected specimens of ATJ-S graphite were nondestructively evaluated and tensile tested in gas-bearing test facilities. The nondestructive test methods used on billets, specimen blanks, and finished specimens were visual inspection, alcohol wipe, radiography, and radiographic enhancement techniques. Correlations were made between nondestructive test indications and fracture location and strength. Low density areas were found to be the predominant weakening defect in this graphite. Fractographic examination of the fractured specimens revealed flaws which could be correlated with those flaws detected nondestructively and predicted from Griffith's theory. (Author).

Download or read book The Quantitative Significance of Nondestructive Evaluation of Graphite and Ceramic Materials written by John W. Orner and published by . This book was released on 1970 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research was to utilize the nondestructive testing (NDT) information, correlations, and techniques developed during previous years for the formulation of an experimental approach for verifying the quantitative significance of nondestructive evaluation of graphite and high temperature ceramic materials intended for aerospace structures and systems. As a part of the program, nondestructive evaluation was carried out on a series of billets of hot pressed diboride compositions of zirconium and hafnium with various additions hot pressed. Two grades of graphite (ATJ and RVA) were investigated to determine the significance of typical defective conditions on the physical behavior of the material. Tensile specimens containing various types of flaws, as determined by nondestructive tests, were broken and the results correlated with the NDT findings. (Author).

Download or read book Bibliography on Fibers and Composite Materials 1972 1978 written by and published by . This book was released on 1978 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bibliography continues and updates previously issued reports by Battelle's Columbus Laboratories information centers on fibers, fiber-reinforced composites, as well as laminate, particulate, and eutectic composite materials. No organic matrix composites or fibers are included. This edition includes 2367 literature references published between January 1972 and September 1978. The references are arranged alphabetically according to author's last name or the name of the organization concerned and chronologically by year of publication. The subject categorization of this edition is similar to that used in the earlier bibliographies. References pertaining only to fibers are indexed as (1) general reviews; (2) growth, forming, or surface treatments; and/or (3) test methods and structural properties. Entries relating to composites are broadly indexed according to matrix materials and specifically by fiber materials. Composites are also indexed (at least once) in the following areas: (1) compatibility studies; (2) theory, analysis, micromechanics, and design; (3) testing and evaluation; (4) application; (5) general review articles; (6) fabrication; and (7) coatings. The report includes both an authors index and a subject index. (Author).

Download or read book Investigation of Nondestructive Methods for the Evaluation of Graphite Materials written by G. E. Lockyer and published by . This book was released on 1966 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: A program of investigation was begun in April 1964, to determine nondestructive methods and techniques for evaluating and characterizing graphite materials. The properties and behavior characteristics of graphite which are important to ablative applications were identified and correlated with the applicable NDT methods and techniques during the first year. Emphasis was directed in verification of the applicability of the various NDT techniques and correlation to characterize graphite in relation to service performance has been an item of major concern. Statistical analysis of these correlations has established the significance of the correlations for predicting the related material properties. An extensive analysis of the application of NDT flaw testing and properties evaluation in regard to quality and reliability is presented. A detailed discussion of infrared technique development activities for measuring thermal properties is also presented. The influence of attenuation and the related effects of frequency distortion on velocity measurements is evaluated and described.

Available in PDF, EPUB and Kindle. Book excerpt: A PROGRAM WAS UNDERTAKEN TO CORRELATE DISCONTINUITIES DETECTED IN GRAPHITE BY NONDESTRUCTIVE MEANS WITH ACTUAL FAILURE LOCATION AND THE APPEARANCE OF THE DISCONTINUITY ON THE FRACTURE SURFACE OF TENSILE SPECIMENS. A SERIES OF 83 TENSILE SPECIMEN BLANKS OF POCO AXF-5Q GRAPHITE WERE ULTRASONIC PULSE-ECHO C-SCAN MAPPED AND THESE DATA COMPARED WITH POST FRACTURE ANALYSIS OF SPECIMEN FAILURE LOCATION AND DISCONTINUITY SIZE. CORRELATION WAS MADE BETWEEN THE C-SCAN MAPS AND FAILURE LOCATION, BUT THE SPECIFIC SIZE OF ACTUAL DISCONTINUITIES WAS NOT ACCURATELY PREDICTED. DISCONTINUITIES LARGER THAN 0.020 INCH MAXIMUM DIMENSION AS MEASURED ON THE FRACTURE SURFACE SIGNIFICANTLY LOWERED THE ULTIMATE TENSILE STRENGTH OF THE GRAPHITE USED IN THIS STUDY.
