Part III-Internal Friction in Glass-Strain Relaxation

JSGT 1954 V38 T548-T560

The elastic after-effect phenomena of a hard borosilicate glass are studied at a range of temperatures from 250° to 500°. The results are used to assess the magnitude of the viscoelastic relaxation and the value of the mean relaxation period. An approximate form of the distribution of the relaxation periods about the mean value is obtained.
