【 摘 要 】

The dynamic fatigue fracture behaviour in different glasses under various sub-threshold loading conditions are analysed here employing an anomalous diffusion model. Critical dynamical behaviour in the time-to-fracture and the growth of the micro-crack sizes, similar to that observed in such materials in the case of quasi-static (``instantaneous”) failures for above-threshold conditions, are predicted and compared with some of the experimental observations in different glasses.
