The character of force and strain measurement testing at LaRC is such that the types of strain gauge installations, the materials upon which the strain gauges are applied, and the test environments encountered, require many varied approaches. In 1997, a NASA Technical Memorandum (NASA TM 110327) was generated to provide the strain gauge application specialist with a listing of recommended procedures for strain gauging various transducers and test articles at LaRC. The technical memorandum offered here is an effort to keep the strain gauge user informed of new technological enhancements in strain-gauging methodology while preserving the strain-gauging guidelines set forth in the 1997 TM. This document provides detailed recommendations for strain gauging LaRC-designed balances and custom transducers, composite materials, cryogenic and high-temperature test articles, and selected non-typical or unique materials or test conditions. Additionally, one section offers details for installing Bragg-Grating type fiber-optic strain sensors for non-typical test scenarios.Moore, Thomas C., Sr.Langley Research CenterSTRAIN MEASUREMENT; STRAIN GAGES; FIBER OPTICS; HIGH TEMPERATURE TESTS; COMPOSITE MATERIALS; BRAGG GRATINGS; TRANSDUCERS; WIND TUNNEL APPARATUS

This Handbook helps to design and build any kind of force measurement equipment for the use in a wind tunnel. It is of interest to those who want to build multi-component force measurement sensors for other applications as well. The book describes the basic relations for the design and presents handbook formulas that can be used to perform a primary determination of main dimensions of a specified multi-component force sensor. This Handbook describes material and manufacturing particularities, instrumentation techniques and methods for the compensation of environmental influences. It also discusses calibration problems of multi-component force sensors and methods for the evaluation of the data.
