Application of piezoelectric transducers and resistance strain gauges for SHM of a metallic integral stiffened airframe panel

Original language description

The paper summarizes the structural health monitoring (SHM) methodology on the metallic integral airframe panel structure loaded by flight-by-flight type of sequence. The experiment and sensor network is described. The results based on the experimental data and SHM evaluation based on piezoelectric transducers (PZT) and resistance strain gauges (SG) are discussed. Data analysis and the subsequent evaluation of the structural health are based on continuously structure monitoring by PZT and SG sensors together with visual monitoring of the fatigue crack propagation using digital cameras. Ultrasonic guided waves (UGW) generated by PZT transducers are able to detect anomalies in the structure based on the damage in between different actuator-sensor positions. The detection capabilities are the strongest when the damage growth is perpendicular and in between the actuator-sensor path. SGs reached very good agreement with the visually based crack growth data and their detection capability was very good. The advantages and detection capabilities of applied technologies can be combined in a smarter way to give a reliable and efficient SHM system in the future. Presented on 9th European Workshop on Structural Health Monitoring (EWSHM 2018), July 10-13, 2018 in Manchester, UK (EWSHM 2018).
