INTERNAL FRICTION IN NON-METALLIC SOLIDS.

Abstract

An apparatus, which permits routine measurement of internal friction as low as 2 x 10 to the minus 7th power and Young's modulus as a function of temperature, frequency, and strain amplitude in extremely low loss materials, is presented. The system described herein can be used to investigate a variety of materials and is not hampered by the limitations placed upon composite resonator systems. It has been successfully used to study internal friction in the amplitude-independent and amplitude-dependent regions in pure and CaCl2 doped NaCl. (Author)
