ABSTRACT:
A method of resonant ultrasonic measurement frequencies to determine materials properties is combined with the use of a finite element model and empirical data made from an actual prototype part to create a validated finite element model. The validated finite element model is then used as a standard for comparison to additional production parts, and production part measurement data is stored and archived by part serial number for future comparison to part tests performed during periodic maintenance of equipment utilizing the part after shipment to customer.
