Abstract

Stack Imaging of spectral amplitudes Based on the Impact-Echo (SIBIE) procedure has been developed at Kumamoto university [1]. This procedure is an imaging procedure applied to the impact-echo (I-E) data. In this paper, an artificial surface-crack was tested using SIBIE and ultrasonics. The test estimated two cases on the depth of surface crack and the effect of water filled in the crack. Comparing estimated crack-depths by the ultrasonic testing with those of the SIBIE procedure, improvement of the crack-depth estimation is demonstrated.
