Abstract

A three-phase method is developed for finding the reliability of cracked anisotropic plates subject to dynamic random excitations. First, the crack trajectory is estimated based on an extension of the maximum energy release rate theory. Second, a random process describing the location of the crack tip on the trajectory is defined by using a generalized Paris-Erdogan model. Third, the probability (reliability) that crack size does not exceed a critical value is calculated. Numerical results are obtained for a thin plate with a crack of initial length 2a0 that is subject to a stationary white Gaussian load. They show that the plate reliability is sensitive to the anisotropic fracture characteristics of the material.
