Book Description
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.

Book Description
The search for an adequate reference strain measuring technique for use in the materials testing laboratory has spanned several decades. Early methods relied on properly calibrated extensometers. Two examples are Tuckerman's Optical Strain Gage and Bergqvist's highly refined inductive and strain gage based extensometers. Length standards were used to calibrate these devices Initially, mechanical displacement mechanisms were used as extensometer checking devices, but with the advent of lasers, the Michelson interferometer has become a dominant displacement measuring tool Advances in stabilizing hardware and electronic detectors have led to the availability of Michelson systems with a resolution better than 5 nm. Microelectronics manufacturing techniques have been used to replicate entire Michelson systems on a silicon chip Advances in detector technology have also led to interferometric linear encoders with resolutions commensurate to classical interferometers. New techniques are being developed that can report strain and do not require initial calibration by displacement measuring instruments Moire interferometry, using a reference grating frequency of 2400 lines mm, has many valuable traits for providing laboratory strain measurements traceable to the National Institute for Standards and Technology (NIST). Experience with strain calibration by more indicates a measurement uncertainty of less than 0.1% corresponding to an accuracy of better than 1 ?m m. Bonded metallic electrical resistance strain gages possess essentially limitless resolution, but accuracy must be established. When properly calibrated, bonded strain gages operating within their elastic range could serve as Class A extensometers. This paper reviews some of the more interesting approaches from the past, analyzes some current methods being investigated, and comments on possibilities for the future concerning the difficult task of finding a suitable calibration technique for use with strain measuring devices.

Book Description
The Springer Handbook of Experimental Solid Mechanics documents both the traditional techniques as well as the new methods for experimental studies of materials, components, and structures. The emergence of new materials and new disciplines, together with the escalating use of on- and off-line computers for rapid data processing and the combined use of experimental and numerical techniques have greatly expanded the capabilities of experimental mechanics. New exciting topics are included on biological materials, MEMS and NEMS, nanoindentation, digital photomechanics, photoacoustic characterization, and atomic force microscopy in experimental solid mechanics. Presenting complete instructions to various areas of experimental solid mechanics, guidance to detailed expositions in important references, and a description of state-of-the-art applications in important technical areas, this thoroughly revised and updated edition is an excellent reference to a widespread academic, industrial, and professional engineering audience.

Book Description
This article points out problems existing in the techniques of authenticating an electric resistance strain gage. After a brief explanation of technical requirements of the electric resistance strain gage in static strain measurements, the test and calibration methods of the double-bridge zero-reading type electric resistance strain gage are introduced. Gage calibration includes three parts, namely, structural inspections, operating performance tests, and calibration. The special feature of the proposed method is that the standard delta R/R used in the calibration is not the resistance change produced by strains in resistance strain strips, but is produced by an electric method; therefore, accuracy is high. Design and construction data for a strain gage calibrator are also given. The calibration methods and calibrator proposed have been proved to have high accuracy by practical application and guarantee that electric resistance strain gage error after calibration will be less than plus or minus 1%.
