This report describes the progress in a program designed to assist the Navy in developing and applying advanced fracture mechanics technology to ensure structural reliability in critical applications of titanium alloys. Phase I of the program which was to gather information and data needed for applying advanced fracture mechanics technology to structural reliability analysis has been completed. The results of this phase are given in terms of a list of areas of concern which must be addressed in the future and a list of pertinent experimental work already completed or in progress. Phase II of this program will use the above information to conduct structural integrity analyses of specific models. A methodology for structural integrity analysis is presented both for general service conditions and accident conditions, which gives an general outline for conducting structural integrity analysis. The method will be applied to specific models supplied by the Navy. A final section of this report describes a method of design for assessing stable crack propagation under load control conditions.
