Simulating the Experiments of the 2005 Ultrasonic Benchmark Study
- Center for NDE, Iowa State University, Ames, IA 50011 (United States)
In the first part of the 2005 benchmark study the pulse-echo response of an artificial crack in a titanium block was obtained experimentally at a number of discrete angles. The second part of the study involved pulse-echo responses obtained from linear scans of a side-drilled hole in an aluminum specimen using both planar and focused probes. These experiments were simulated by ultrasonic measurement models and the model-based and experimental results compared. A multi-Gaussian beam model was used to model the ultrasonic wave fields present in all cases studied and the Kirchhoff approximation was used to predict the scattering from the crack. The Kirchhoff approximation and method of separation of variables were used to model the wave scattering from the side-drilled hole. A discussion of the model and experimental comparisons is given.
