ABSTRACT:
The invention simulates acoustic emission signals produced by crack growth within a structure so that listening equipment may properly be calibrated to listen for acoustic emission signals from actual structural crack growth. The invention has several embodiments which generate acoustic emission signals from a crack growing in a specimen such that the acoustic emission signals have a broad bandwidth as the crack grows. The acoustic emission signals produced by the growing crack can be introduced into a structure being monitored through a cone-shaped portion which is bonded to the structure being monitored.
