Structural health monitoring of a wing-panel splice joint using acoustic emission
Original language description
This paper documents the usage of an acoustic emission (AE) method for health monitoring of a typical airframe structure joint - a splice joint of a bottom wing integral panel and a build-up panel of a commuter aircraft. Fatigue tests of representative specimens for the splice joint were carried out. Continuous acoustic emission measurements were supported by crack detection using crack wire (CW) detectors and by visual monitoring of crack propagation using digital cameras. The CW detectors bonded on the surface of the specimens around the splice joint critical areas proved to be very suitable for crack detection in the early stage of its propagation. Data analysis and the resulting evaluation of structural health continuously monitored by the AE method are presented. AE reached very good agreement with the visually based crack growth data, although the acoustic signals arising from individual fasteners (rivets) caused noise in the data. Cumulative root-mean-square (RMS) dependency on the crack length is presented, for considering crack growth prediction possibilities
