Computation of Probability Distribution of Strength of Quasibrittle Structures Failing at Macrocrack Initiation
Original language description
Engineering structures must be designed for an extremely low failure probability, i.e. Pf < 10-6. To determine the structural strength corresponding to such a low failure probability, a physical model of the probability distribution of structural strength is required. Recent study showed that the strength distribution of quasibrittle structures, which fail at the macro-crack initiation from one representative volume element (RVE), can be statistically modeled as a finite chain of RVEs. It has been further demonstrated that, based on atomistic fracture mechanics and a statistical multi-scale transition model, the strength distribution of each RVE can be approximately described by a Gaussian distribution, onto which a Weibull tail is grafted from the far-left end a point of the probability of about 10-4 to 10-3. The model implies that the strength distribution of quasibrittle structures depends on the structure size, varying from the Gaussian distribution modified by a far-left Weibull t
