| Abstract: | The brittle fracture probability and reliability are obtained in terms of dislocation mechanism of microcrack evolution. The statistical distribution functions and statistical deviations of elongation, strength, plastic work, crack extension force, fracture foughness, critical and crack length, can be derived in a unified fashion. |

| Keywords: | fracture probability rel iabi 1 ity fracture strength crack extension force fracture foughness statistical distribution function |
