Lessons Learned and Contextual Framework

Key lessons learned from aging aircraft and other research over the past four decades showed that  

Fracture mechanics need to be considered in the context of a modern design paradigm. Such a contextual framework and simplified flow chart is given in Fig. 1.5. The paradigm needs to address the following  

A schematic flow diagram that underlies the processes of reliability and safety assessments is depicted in Fig. 1.6. The results should be used at different levels to aid in operational and strategic planning.
