Continuous acoustic emission monitoring by data streaming oscilloscopes
Original language description
Acoustic Emission (AE) method widely used for non-destructive evaluation and material characterization is very beneficial for monitoring of highly dynamic damage processes. Computational power of contemporary regular hardware enables to test the new approaches in this field as it could not be done before without the capability of continuous signal recording and analysis. Modern portable measuring devices as USB oscilloscopes with data streaming feature can be flexibly controlled by scripts tailored for particular experiment. AE activity can be thereby evaluated on-line in more detail by specially designed parameters. The running experiment can be controlled by actual state of material damage as well. Such approach is demonstrated during the test of titanium alloys for orthopedicnimplants. The AE method provided comprehensive data to identify the initial stages of damage and crack propagation in the stressed specimen. AE measuring and evaluating system based on USB oscilloscope TiePie was completely designed and run in Matlab environment, displaying basic AE parameters, audibly monitoring captured AE hits and saving those parameters together with the complete signal stream in binary format for further advanced analysis.
