Fatigue sizing of composite structures

Software tools
Commercial finite element calculation codes (ABAQUS, ANSYS...) do not perform fatigue calculations, but calculate for a given number of cycles. The material characteristics then correspond to the residual properties for the number of cycles concerned. The question then remains: for which cycles is it wise to perform these calculations? The answer can be found in the cycle skipping techniques mentioned in [AM 5 410] § 8.2....
