摘要:
A simplified bridge system for measurement of internal friction and fractional variations of Young's modulus at kilohertz frequencies is described. The system, composed of commercially available components, is used with a two‐part composite oscillator and is capable of measuring (logarithmic) decrements ranging from 10−7to 10−2. Fractional variations of decrement and Young's modulus can be detected to within 0.5% and 0.1 parts per million, respectively.
