Abstract

In the early 1970s the National Aeronautics and Space Administration sponsored a series of studies designed to quantify the reliability of the common nondestructive inspection methods. The results of those studies became the basis for the assumed minimum initial crack sizes contained in NASA fracture control requirements and the fracture analysis software, NASA FLAGRO. The origin of the assumed initial crack sizes is described along with the current program for verifying inspection reliability. The suitability of the current program is assessed and options for improving the program are discussed.
