Abstract
Fracture of lapped brittle plate exhibits a random and uncertain property. In this study, based on a finite element division and the fracture mechanics of micro surface cracks, a numerical prediction approach for fracture cumulative distribution function (CDF) for lapped brittle plate under non-uniform stress field is proposed. Applications under different conditions are carried out, and influences of abrasive size and crack density on the proposed prediction method are discussed. The predicted Weibull parameters are in good agreement with experimental results, which establishes validation and potential engineering value of the proposed prediction method.
