Abstract
A probabilistic methodology was developed for fracture-mechanics analysis Of nonlinear cracked structures. It involves nonlinear finite element analysis by the well-known commercial codes, statistical models for uncertainty in material constitutive law, fracture toughness, and loads, and standard reliability methods for evaluating probabilistic characteristics of elastic-plastic fracture parameter. Numerical examples are presented to illustrate the proposed methodology for two- and three-dimensional cracked structures. The results from these examples show that the methodology is capable of predicting accurate deterministic; and probabilistic characteristics of J-integral for their use in elastic-plastic fracture mechanics.
