FUNDAMENTAL MODELS AND MEASUREMENTS FOR ULTRASONIC NONDESTRUCTIVE EVALUATION SYSTEMS
It will be shown that it is possible to completely characterize an ultrasonic nondestructive flaw measurement system and simulate the measured flaw signals. This characterization includes the pulser/receiver, cabling, and transducers present as well as the propagating and scattered acoustic/elastic wave fields. All the elements of this comprehensive ultrasonic measurement model will be discussed as well as practical methods for obtaining those elements through a combination of models and measurements.
