Monitoring of Crack Propagation Using a Cluster of Piezo-sensors

  title={Monitoring of Crack Propagation Using a Cluster of Piezo-sensors},
  author={Stuart Wildy and Chian Guan Lee and Shi Yong},
This paper describes the investigation of a probabilistic method for crack propagation monitoring in plate- or shell-like structures, which utilises a cluster of passive piezoelectric sensors. The method allows for the determination of the crack tip location and stress intensity factor (SIF) of a relatively long crack in the vicinity of the cluster, with predetermined or specified accuracy of monitoring. An analytical deterministic model for the response of a piezo-sensor located in the… CONTINUE READING
