Abstract: Estimation of the shortest wave-path is a crucial task not only in the field of acoustic emission (AE) source location. Recently designed method for solving the problem was inspired by Huygens' principle as easy to implement alternative suitable for discretized 2D or 3D 'bitmap' pictures of a body. This approach also enables tracing of elastic waves propagating in structures of complicated shapes without mathematical models and collecting sufficient amount of representative data for AE source location algorithms based on database searching or artificial neural networks. The new method already showed its advantages and potentialities in practical tasks as discussed.
Keywords: acoustic emission; discrete bodies; non-destructive testing; shortest ways finding
