Zusammenfassung

Große zylindrische Stahlprüflinge werden mittels der Methode der finiten Differenzen im Zeitbereich (engl. finite differences in time domain, FDTD) simulativ untersucht. Dabei werden Pitch-Catch-Messanordnungen verwendet. Es werden zwei Bildgebungsansätze vorgestellt: ersterer basiert auf dem Imaging Principle nach Claerbout, letzterer basiert auf gradientenbasierter Optimierung eines Zielfunktionals.

Abstract

Huge cylindrical steel hubs are simulatively examined with the method of finite differences in time domain (FDTD). Pitch-catch arrangements are used in these examinations. Two approaches to imaging are presented, one based on Clearbout's “Imaging Principle”, and one based on gradient-based optimization.
