THE PROBABILITY AND STATISTIC METHOD AND ITS APPLICATION TO BRITTLE FRACTURE
|
Abstract:
In this paper,a probability and statistic equation for brittle fracture is proposed based on the concept of individual cumulative fracture probability.It is related to the defect density and the cumulative fracture probability,as well as the stresses.Some previous fracture probability and statistic equations are shown to be special cases of this equation and the defect density and the cumulative fracture probability play an important role.The number and the distribution of the fragments are obtained from the equation and the related probability and statistics.
