MICROPROCESSOR UTILIZATION IN ULTRASONIC INSPECTION FLAW GROWTH CLASSIFICATION STUDIES

The underlying purpose of this study was to demonstrate the applicability of microprocessors to the ultrasonic inspection field. The importance of using microprocessors to perform ultrasonic data acquisition and signal analysis is to allow the large, laboratory based computers used for traditional signal processing to be replaced by smaller, inexpensive, and portable processing units. Thus the computing power now limited to the laboratory could be transported into the field. The emphasis of microprocessor implementation was directed initially towards ultrasonic inspection problems of interest to the U.S. Navy, in particular that problem of inspecting ship hull plates. A second task is also included as part of this microprocessor feasibility study. An advanced ultrasonic inspection problem, that of fatigue crack growth determination, was developed as a possible implementation test for the microprocessor.
