Geodetic Iterative Methods for Nonlinear Acoustic Sources Localization: Application to Cracks Effects Detected with Acoustic Emission
Original language description
This paper is related to Acoustic Emission (AE) principle, which is a Nondestructive Testing method (NDT) for structural health monitoring and many other applications. We deal with the geodetic curve based localization of the defects on surfaces of solidbodies mathematically described as a conjunction of several simpler parametrized shapes like cylinders, toroids, spheres, cones,... with intersections. We demonstrate a numerical solution of geodesic equations by the algorithm Newton-Raphson method. Forfaster computations we propose a few improvements using Sequential algorithm applied to bisected points of the intersections, which is compared with trivial Fundamental method. The whole algorithm for finding geodesics on combined surfaces is applied tovirtual testing body which was designed according to the solid watering can.
