This work directly applies the weakest link formulation of cumulative failure probability for synchronized analysis of both size dependence and random variation of particle strength. This approach is justified from two aspects: First, the breakage of brittle particles belongs to brittle fracture, which is commonly described by the weakest-link postulate. Second, the weakest link postulate allows considering different statistical distributions in addition to the Weibull distribution. Eight sets of published breakage strength dada of different sized glass spheres and irregularly shaped grains made of different materials are proven to fall onto a master curve dictated by the weakest link statistics model.
