Acoustic source location by time reversal signal transfer from experiment to numerical model (digital twin)
Original language description
Reliable and relatively precise location of Acoustic Emission (AE) sources is one of the most important inverse problems in non-destructive testing and structural health monitoring of engineering structures. Standard AE source location procedures often fail in a case of more complicated structures with wave dispersion, propagation velocity or geometry changes, etc. Very effective tool in such situations became some years ago time reversal (TR) signal processing. Advantages of TR based source location are in its high precision and elimination of problems connected with dispersion, attenuation, reflections, etc. in relatively simple way. Disadvantage of that method consists in necessity of detailed scanning the structure surface for searching location of the vest source reconstruction. However, more effective solution is TR transfer of detected signal from the real structure onto its numerical model and location of the source here.
