COMPARISON OF THE INSPECTIONS OF SMOOTH AND ROUGH CRACK-LIKE DEFECTS USING ULTRASONIC ARRAYS

Abstract

The use of ultrasonic arrays to detect crack-like defects is an important area in non-destructive evaluation. The array data, which contains scattered ultrasonic waves from a scatterer, can be used to reconstruct a high resolution image, e.g., using the total focusing method (TFM). In this paper, the TFM images from smooth and rough crack-like defects are compared. It is shown that roughness can be either beneficial or detrimental to the detectability of crack-like defects.
