Effect of the internal stress
in quartz glass on the internal friction
Abstract
Influence of internal stress
in silica glass on internal friction was investigated. The experimental data
shows that dependence of internal friction in silica glass on its location in
large glass block connected with nonuniform distribution of internal stress in
the silica glass block. Energy of activation of the dissipation process that
connected with internal stress in KU-1 and KS4V silica glass was determined.
Annealing of silica glass leads to elimination of this internal friction
however during annealing grown of defects of surface layer and grown of loss in
this surface layer takes place.
