Abstract

Based on the weakest link model and linear elastic fracture mechanics, an equation of the defect detection probability PD is derived theoretically. Assuming that the fracture strengths before and after repair of the detected flaws both follow two-parameter Weibull distributions, the equation PD=1−(a/ϵ)−κ, (κ>0, ϵ>;0), is obtained for large a. An insight into the distribution of the size of the detected flaws is also obtained.
