Geodetic Iterative Acoustic Emission Source Location with Constant Elastic Waves Velocity Elimination
Original language description
This paper deals with the AE source localization based on precise computations of geodesics on a given surfaces. Newton-Raphson procedure is implemented for the geodesic equations computation purpose. On this basis, new efficient variants of localizationalgorithms employing Direct Search Methods (Compass algorithm, Reduced Newton method and Nelder-Mead method) for minimizing distinctions between the real measured time differences and the computed length differences found via geodesics is developed. This approach allows to eliminate constant AE waves velocity. The aggregated procedure is applied to our own experiment on the Galvanized Steel Watering Can that represents a vessel with higher geometrical complexity.
