Combined Impact and Fatigue Loading in CFRP: Effects of the timing of an impact event during cyclic loading of composite aircraft structures

This research experimentally investigates the effects of an impact event during fatigue loading of a CFRP structure. Open-hole specimens were impacted in-situ during a short interruption of a tension-tension cyclic loading program. The impact was aimed directly below the central hole, with the critical fatigue damage path being left and right of...
