Abstract

It is of great significance to monitor and quantify the defects in the thin segmental spherical shell components. In the paper the guided wave's inspiring method has been obtained from the wave-mode conversion based on the theory of the guided wave propagating in the thin spherical shell. Using the wavelet to process the testing signal, and the ellipse localization imaging algorithm, the defect's localization and orientation can be detected accurately. Experimental results show the defect's direction and location can be detected effectively and clearly.
