A Novel Ultrasonic Vibration Analysis Technique for Defect Detection

A novel ultrasonic vibration analysis technique was developed for damage detection in complex structures with the intention of combining low-frequency (i.e. non-ultrasonic) modal analysis and ultrasonic transient wave inspection methods. A guided wave vibration decomposition method was derived to demonstrate that steady-state structural vibrations can be described as a superposition of guided waves propagating within the structure. The ultrasonic loading function (i.e. actuator frequency and phasing) applied to an annular array transducer was varied, allowing for a greater range of defect sensitivity during key experiments on a number of test samples.
