PRECISION MEASUREMENT OF INTERNAL FRICTION IN NON-METALLIC MATERIALS.
Abstract
Internal friction measurements were made on an outstandingly good quartz crystal. Several internal friction peaks are observed and these are discussed. In addition a previously unreported anomaly is observed in the resonant frequency versus temperature curve for the quartz crystal. These measurements were made over a temperature range of approximately -125C to 300C. The internal friction of sodium chloride was measured at room temperature in a free decay apparatus. (Author)
