New ultrasonic monitor to determine crack-opening load in compact tension specimen uses transducers to pass acoustic wave across crack region. Definite improvement in signal-to-noise ratio. Process possesses substantial immunity from noise caused by operation of load frame and associated parts. In addition to applications for aerospace community, this monitor and concept clearly have general utility in testing of materials and potentially in nondestructive evaluation of solid parts.
