Abstract

We propose a framework for crack size measurement using a time domain signal of subharmonic waves. In analogy to the resonant characteristics of subharmonic vibration of bubbles in liquids, we formulate an equation for resonant excitation of subharmonic wave at partially closed cracks. The equation has been partially verified by comparison between experimental and calculated waveforms. Crack size measurement by a phased array is also described.
