Stress-dependent vibration peaks in glass - Literature results

When glass is subjected to mechanical stress, it is found that the IR- and Raman lines are shifted relative to their position in the stress-free state. It is shown that for almost all lines a decrease in the wave number occurs under tensile stresses and an increase under compressive stresses.
When plotted against the maximum stress component, larger changes in wave number are generally observed in hydrostatic compression tests compared to tensile tests. When plotted againstthe hydrostatic stress component, the slopes under compression and tension are quite comparable.
We made a short literature review on experimental measurements. It can be seen that in the range of about 1060/cm to 1120/cm the influence of stress in both the tensile and compressive ranges is almost negligible.
The reason for this abnormal behavior will be investigated in a separate study.
