Description

There currently exists a widespread need for the development of quantitative methods for the nondestructive evaluation of cylindrically shaped components such as a helicopter rotor hub. Of particular interest is a geometry, which consists of an outer hollow cylinder and an outer hollow cylinder with a solid inner shaft. Unfortunately, conventional ultrasonic methodologies (such as pulse-echo) often fail to detect these cracks, mainly because of a lack of accessibility and the inherent complexity of the waveforms generated.
