The activities presented are aimed at integrating in the same numerical approach both the prediction of the residual strength of a composite structural detail in the presence of damage and the evaluation of the crack growing rate under cyclic loading, so to represent a valuable tool for the design of damage tolerant composite aircraft and rotorcraft structures
