Helicopter rotor systems are increasingly using flexible composite structures to provide the required control movement for the rotor blades. These structures such as rotor head flex beams can experience very high surface strains, which can be in the order of 15,000 με. ...Helicopter rotor hubs incorporating thick composite flexures are subjected to delamination failures with correlate to bending excursions.
