Abstract
The development is described of a novel Probabilistic Fracture Mechanics (PFM) code based on the three-dimensional J-integral database, giving so-called fully plastic solutions. An efficient technique for the evaluation of leak and break probabilities is also utilized, based on the Stratified sampling Monte Carlo simulation (SMC). The outline of the present PFM code is described, and the J-integral database and the numerical technique are presented. Nonlinear effects of materials on failure probabilities are discussed through the analysis of a surface cracked structure subjected to cyclic tension.
