ABSTRACT:
A method and apparatus for determining the performance level, amount of wear, and remaining useful life of a new or worn object, preferably of metallic construction through harmonic fatigue evaluation. The object to be tested is struck with a resonant frequency generating device, causing the object to transmit its vibrational resonance to at least one signal receiving transducer. The transducer then relays the frequency back to a database wherein it is compared to known frequency responses of that specific object through a linear continuum from prior controlled testing, to determine the remaining performance level in comparison to a new object of the same construction.
