Description

It is becoming fairly routine to detect flaws in structures by ultrasonic methods. However, the characterization of flaws, once they are found, is much more difficult. We will present a method called “shadow imaging” for the visualization of surface-breaking crack-like flaws using ultrasonic imaging. Shadow images provide an easily interpretable record of the crack depth profile, and also an indication of the degree of crack closure.
