Testing of the Method of Cluster Analysis of the Arrays of Acoustic Emission Pulses in Case Study of Glass Granulate Heap Formation
Testing methods of cluster analysis and classification of the recorded arrays of pulses of acoustic emission (AE) is used to detect crack-induced AE signals in the brittle layer of tense-sensitive coating and also to reveal different phases upon transition from the regular to avalanche process of damage accumulation in the physical simulation model. Such phases of damage accumulation are simulated for the process of glass granulate cone formation and then detected using AE control system synchronized with a camera of high speed movie recording.
