Title:
THE APPLICABILITY OF A FRACTURE MECHANICS-NONDESTRUCTIVE TESTING DESIGN CRITERION

Abstract:
This report describes the work conducted on a program designed to investigate the potential applicability of a combined fracture mechanics- nondestructive inspection procedure as a design approach for aircraft structures. The program consisted of three phases, conducted simultaneously 1 a literature survey to determine if sufficient fracture toughness information exists to determine a statistically valid value of K1c 2 a test program to determine the minimum size of a crack that can be detected by each of four NDT methods X-ray, magnetic-particle, penetrant, and ultransonics and 3 a test program to determine if fracture mechanics, when combined with flaw size as determined by NDT, can accurately predict the failure load of selected structures.
