Digitally controlled measurement of sonic elastic moduli and internal friction by phase analysis

An automated system is described for measuring internal friction and elastic moduli using sonic resonance techniques. This mirocomputer‐controlled device does phase angle analysis in addition to traditional decay and peak‐width internal friction measurement. The apparatus may be programmed to make m...

Description
Summary:An automated system is described for measuring internal friction and elastic moduli using sonic resonance techniques. This mirocomputer‐controlled device does phase angle analysis in addition to traditional decay and peak‐width internal friction measurement. The apparatus may be programmed to make measurements at any sequence of temperatures between room temperature and 1600 °C.
