| Abstract: | Time-dependent fracture is considered. The damage distribution ahead of crack tip
is analysed The range of applicability of the characterizing parameter for the creep
crack growth is discussed on the basis of fracture mechanics and continum damage me-
chanics. The creep crack growth rate is determined under certain conditions. |

| Keywords: | Time-dependent fractur creep damage crack growth rate |
