ABSTRACT:
Methods for the prediction of the frequency of high order resonant ultrasound spectroscopy (RUS) diagnostic modes are used to limit the band width of diagnostic testing at high order mode frequencies. Testing of parts at low order frequency modes is used to calculate part dimensions, and then these calculated part dimensions are used to predict high order diagnostic mode frequencies. Lower order mode frequencies are used to predict high order diagnostic mode frequencies.
