Book Description
Recent developments in experimental and computational capabilities suggest an opportunity to develop improved models of crack growth for use in life management of materials and components in advanced gas turbine engines. Improvements in such models have potential benefits in the sustainment of aging engines, as well as the design of more durable future engines. Current approaches for life management of engine components tend to ignore potential increases in crack propagation lifetime that may occur as the result of load interaction phenomena under variable amplitude spectrum loading. In effort to quantify these potential benefits, a study of updated mission profiles was performed. A variety of engine usage spectra were surveyed to document their cycle content statistically, including characterization of the fundamental load sequence events and the expected severity of damage produced by these events, using data from the advanced nickel-base superalloy IN100.

Book Description
The Structures and Materials Panel is co-ordinating a series of four Workshops planned within the framework of a Review on Damage Tolerance for Engine Structures. The Review aims to address the areas critical to the acceptance of an approach based on damage tolerance concepts as an alternative lifing philosophy to that of 'safe-life' for the design of engine components. Workshops have been held at two previous Panel Meetings dealing with 'Non- Destructive Evaluation of Components, AGARD R-768' and 'Defects and Quantitative Materials Behaviour, AGARD R-769'. The third Workshop was held during the sixty eighth Panel Meeting and surveyed current approaches to the prediction of component behaviour and the establishment of suitable inspection schedules. The role of testing and life management planning in these approaches was examined. Future technology requirements and the need for a common AGARD approach were discussed. This publication includes the presentations made in the course of the third Workshop, together with Recorders' Report of the discussions.
