This work aims to apply Acoustic Emission monitor the drilling process in carbon fibre laminates. Continuous data is captured over entire of a through hole. The use continuous acoustic emission acquisition allows identification lower frequency periodic temporal features related cutting process. A new approach analysis presented that utilises an enveloping technique study these phenomena and sho...

In the first half of the article, inspection organization and programs are briefly dealt with. This is followed by a more detailed review of inspection, detection and monitoring methods, which comprises visual inspection, radiography, ultrasonic testing, eddy current technique, magnetic particle inspection, the use of liquid penetrant, the electric field signature method, acoustic emission, lea...

Acoustic -emission techniques are beginning to be frequently used as a means of detecting and locating deformation and fracture processes in both metallic and non-metallic engineering structures. This has happened despite a relatively poor understanding of the basic physical processes involved in the generation, propagation, and detection of acoustic -emission signals, and of the influence in m...
