4 answers
Fatigue testing on fused silica glass involves various methods to assess its resistance to repeated stress. Uni-axial compression tests with constant force or displacement amplitude, fixed upper displacement limit, and bending constant displacement amplitude tests are common approaches. These tests reveal that fatigue failure in fused silica glass is attributed to the degradation of interlocking in the crack wake, with crack initiation often linked to the cracking of larger grains. Additionally, multiple-pulse laser damage experiments on synthetic fused silica at different wavelengths demonstrate a fatigue effect due to cumulative material modifications, impacting the material's long-term integrity.
