Description

Physical models can play several important roles in developing and evaluating ultrasonic techniques for the inspection of titanium engine components. In conventional inspection, models predicting signal-to-noise ratios can be used in system optimization. Models synthesizing time-domain wave forms can also be utilized to evaluate advanced signal detection algorithms. Finally, models can play a major role in probability of detection (POD) assessment, being used as tools to simulate (1) effects of measurement system and scan plan selection, flaw morphology and microstructure on the distribution of flaw responses; and (2) effects of measurement system microstructure on the distribution of noise.
