In ultrasonic testing of complex shaped parts such as turbine blade roots, it might be difficult to distinguish echoes from defects and component corner parts. Simulation software for ultrasonic testing plays an important role in avoiding false calls when there is a lack of mock-ups and reference induced defects. CRIEPI has developed high speed simulation software to predict B scope images for defects, based on the geometrical theory of diffraction (GTD) to calculate ultrasonic waves transmitted from an angle probe. Analytical equations have been newly derived to express echoes received by the probe. This paper deals with applicability of the CRIEPI's software to prediction of B scope images constructed from the test data of complex shaped part.
