Description / Abstract:

This test method describes a procedure for measurement of ultrasonic velocity in structural engineering solids such as monolithic ceramics, toughened ceramics, and ceramic matrix composites.

This test method is based on the broadband pulse-echo contact ultrasonic method. The procedure involves a computerimplemented, frequency-domain method for precise measurement of time delays between pairs of echoes returned by the back surface of a test sample or part.

This test method describes a procedure for using a digital cross-correlation algorithm for velocity measurement. The cross-correlation function yields a time delay between any two echo waveforms (1).2
