Stress-enhanced swelling of silica: Effect on residual deformation of bent fibers

Fett, Theo; Schell, Günter

The deformation of water-affected silica fibers in 2-point-bending does not completely disappear after unloading. So far, this effect is discussed in literature as a stress relaxation at rather low temperatures. In the present study, we apply the swelling concept to the literature measurements. We found that the predictions of residual deformation via volume swelling by hydroxyl generation are in good agreement with the available experimental results.
