Acoustic Emission Crack Detection by Means of Iterative Procedures Based on Geodesics

Popis výsledku v původním jazyce

Acoustic Emission (AE) as a Nondestructive Testing (NDT) method is described. Defect localization principle is based on precise computation of geodesics on the surfaces of tested bodies. The geodesics will be described by geodesic equations, which include information about the surface shape. We can simulate the real surfaces from engineering industry by means of compositions of elementary surfaces, on which geodesics are computed using the well-known Newton-Raphson algorithms. We localize the AE sourcesby means of minimizing the Euclidean distance between the differences obtained from geodesics and the real measured time differences. For this purpose we use Direct Search Methods, namely Compass algorithm, Reduced Newton method and Nelder-Mead method.
