The paper illustrates some of the important factors affecting the accuracy of proven analysis techniques in support of a damage tolerant design methodology. Temperature sensitivity analysis and the relevance of component geometry in controlling material response to external loading are discussed. The requirement to translate characterised material behaviour into models suitable in stress analysis is demonstrated. Examples identifying critical stresses and critical locations in typicel engine discs are presented. The implementation of fracture mechanics analysis methods to these regions is discussed. Finally their relevance to damage tolerant design concepts is evaluated.
