FUNDAMENTALS OF THE STATISTICAL THEORY OF FRACTURE

The first important study of fracture statistics was that of Weibull. His work was based on the tacit assumption that only the component of stress normal to a crack plane contributes to its fracture, and on the use of simple analytical formulas for failure probability. Recent progress in short-term fracture includes the use of more refined fracture criteria and a search for better distribution functions for the frequency of cracks, based on micro-structural considerations. Use of the critical value of strain energy release rate as a fracture criterion leads to improved agreement with experiment. Consideration is also five to the statistics of fracture in static fatigue and in dynamic fracture.
