A compact instrument to measure the strain history of a point on a resonant structure of a flight vehicle is considered. The output data from the instrument is designed to aid in the estimation of acoustic fatigue damage. The ability of a strain gage to perform under fatigue conditions is examined. The design of circuitry to modify the sonic recorder discussed in Volume I (AD-295 464) to a response recorder are discussed. Performance data of the bread boarded response recorder, tested with a resonant structure, are given.
