... 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. ...
