Available in PDF, EPUB and Kindle. Book excerpt: A summary is presented of a research program aimed at the improvement of high-temperature strain gages of the electrical resistance type. Potential ceramic and metal components were evaluated and a gage was devised that was based on these evaluations. This gage (NBS 5B) was flexible and easy to install; however, it lacked resistance stability at higher temperatures. In an attempt to minimize this deficiency, ceramic cements were developed that showed greater electrical resistivity than had been previously observed in the range 800 to 1800 degrees Fahrenheit; also, a technique was devised for increasing the resistance to ground by applying a fired-on ceramic coating to the grid of a specifically developed unbacked gage. A study was made of the cause of the erratic response of cemented gages that had not been preheated prior to use. There were strong indications that the erratic response was caused mostly by the rapid decrease in resistance that accompanied structural changes in the cement.

This book was released on 1992-04-30 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental stress analysis is an important tool in the overall design and development of machinery and structures. While analytical techniques and computer solutions are available during the design stage, the results are still dependent on many assumptions that must be made in order to adapt them to the problems at hand. One popular method of finding structural and design weaknesses is through the use of the electrical resistance strain gage. These devices are relatively low in cost, easily applied by a reasonably skilled technician, and require little investment in instrumentation (for the general user), yet they yield a wealth of information in a relatively short time period. The information and its validity is, of course, dependent on the training and knowledge of the engineer who plans the tests and reduces the data. In addition to serving as a reference for engineers, this practical, instructive book has a high potential as a textbook for senior and first-year graduate students in engineering and related fields, such as engineering physics and geology. A solutions manual is available to instructors using the book as a text.

This book was released on 1970 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pertinent conclusions from an extensive study at the Liquid Metal Engineering Center (LMEC) of the accuracy and performance of high-temperature strain gages are presented, with particular emphasis on that portion of the study pertaining to an evaluation of 16 Armour D-platinum gages fabricated at the LMEC for use up to 1200 F. (Armour D alloy is 70 percent iron, 20 percent chromium, and 10 percent aluminum.) Test apparatus and procedures used to evaluate these gages are described. Variations in gage-to-gage performance, as a function of the test sequence, are analyzed on a statistical basis to assess gage accuracy. It is concluded that there are no suitable commercial gages for the measurement of strains on liquid metal fast breeder reactor (LMFBR) components at temperatures up to 1200 F, and that the Armour D-platinum gage performed better than any of the commercial gages similarly evaluated at the LMEC for use up to 1200 F. The presentation should be of particular interest to those involved in high-temperature strain measurement, or in the interpretation of high-temperature strain measurement with respect to structural or materials behavior.

This book was released on 1965 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Centaur liquid-hydrogen tank at station 402 was instrumented with four strain gage installations on the Atlas-Centaur AC-3 flight vehicle. These gages were subjected to an extremely severe environment both during vehicle assembly at Cape Kennedy and during flight when the temperature at the gage was -423 degrees F. This report covers the installation of the gages, the signal-conditioning equipment and system calibration, and analysis and evaluation of data obtained from the flight. In spite of the severe environment both before and during the flight, useful data were obtained to evaluate structural performance. Incremental loads from launch to booster engine cutoff obtained from the strain gages were compared with the values computed from known mass distribution and gravity environment. Of the values at the four gage locations, two agreed almost exactly with the calculated values. Of the other two, one differed by 12 percent and the other by 15 percent. Although bonded gages have been in use in the laboratory at liquid-hydrogen temperatures, this technique on flight vehicles presented many problems. The results indicate, however, though the bonding process is a painstaking one, such gages can be a valuable tool for evaluating flight structural performance.
