From initial damage to ultimate failure, there is a range of loads that structures can undergo while still keeping within the safety requirements. Mastering this damage tolerance would enable to operate an aircraft with damaged structures, providing the remaining capabilities could be certified. In order to integrate damage tolerance in the design and the maintenance in a cost-effective way, numerical tools should enable the calculation of damage initiation and propagation: a thorough mastering of the modeling, the computation, and the experimental characterization of damage evolution has to be achieved. This paper summarizes the EADS's global approach to hit this target.
